3 STEPS
The combination of a strong
Session Border Controller and
Lync enables corporations to
reduce CapEx and OpEx, improve
network availability, take advantage
of modern applications, boost
employee productivity, and
enhance enterprise security.

COMMUNICATION IS KEY TO SUCCESS in
today’s highly competitive, global marketplace.
Executives need to make decisions quickly, but
information and employees are spread out in many
different locations. To operate efficiently, businesses
need fast, simple ways to exchange data.
As a result, many enterprises stand at an impor-
tant crossroad. They have invested large sums in
legacy Time Division Multiplexing (TDM) network
voice infrastructures that do not easily support
modern Unified Communications (UC) solutions,
such as the increasingly popular Microsoft Lync.
Unified Communications (UC) is the next stage in the evolution of enter-
prise communications and collaboration technologies, bringing all varied
connections under a single architecture. This process makes communi-
cation seamless, no matter where you are or what device you use. These
communications can be delivered over an Internet protocol (IP) network
through voice, video and data. One of the most compelling benefits of UC
is its ability to empower mobility. Unified Communications doesn’t limit
enterprises to the desktop; UC platforms can support mobile devices as
fully integrated clients. To make this work, enterprises need a working
data connection on a mobile device and a UC app installed on the device
by the IT department or through an app store. It’s that simple.
Microsoft Lync is an enterprise-ready Unified Communications
platform. Lync connects people everywhere, on desktop and mobile
devices, as part of their everyday productivity experience.
“About 70% of businesses are now using Lync in some fashion,” states
Irwin Lazar, Vice President and Service Director for The Nemertes
Research Group, Inc. “Most of these companies use it for instant
messaging, web conferencing, and voice/video chat. A small but
growing percentage are using it to replace or augment their PBXs.”
In addition to delivering new communication options, Unified Commu-
nications delivers other benefits. By leaving behind their legacy PBX
and moving ahead to a new Session Initiation Protocol (SIP) network
infrastructure, businesses reduce their capital expenditure (CapEx)
and lower their ongoing maintenance requirements, which can
decrease their operating expenditure (OpEx) by as much as 50%.
The transition from the old to the new works with the right network
infrastructure. Enterprises need one that is rock solid. “Today,
businesses simply cannot tolerate downtime,” says James Rodd,
Co-Founder and Managing Director at Modality Systems, Unified
Communications specialists. Businesses must also have a way to
integrate their traditional systems with new, modern functions. Finally,
they need a solution that offers robust security, so corporate data
is protected as it travels from location to location. To deliver such
functionality, enterprises need a Session Border Controller (SBC) that
works in conjunction with Lync to enable the delivery of sophisticated
voice, data, and video services to enterprise users.
How Lync Enterprise Voice Benefits Corporations
In many cases, business communication is being stymied because
the design of traditional PBX voice systems has become anti-

®
quated. These solutions were designed with a single purpose: to
carry voice communications, and thus they offer limited integration
with new communication options. Consequently, they do not work
well with multimedia communications or new collaboration tools.
Another problem is these systems often tie users to their desks:
these solutions were not built for wireless communications and
thus do not readily integrate with cellular and Wi-Fi networks or
mobile devices.
Lync Enterprise Voice delivers businesses a better platform, one that
integrates scattered corporate communication pieces together. On
the voice side, Lync Enterprise Voice provides numerous enhanced
calling features:
CALL FLEXIBILITY: Click-to-call a contact, hold, forward, transfer,
divert, park, or retrieve
SIMPLICITY: Users click on a contact card displayed on their
computer screens and calls are placed over Public Switched
Telephone Networks (PSTNs) or Voice over Internet Protocol (VoIP)
networks
DEVICE SELECTION: Employees receive incoming communi-
cations simultaneously on all of their communications devices,
enabling them to answer with the most convenient one
Lync is highly cost-effective. “By moving to Lync, businesses can simplify
their UC architecture–eliminating separate PBXs and thus reducing
licensing and operational costs associated with running a separate
platform for telephony,” notes Nemertes Research’s Lazar. Users enact
moves, adds, and changes themselves, so the IT staff spends time on
more meaningful, revenue-producing tasks.
With a new enterprise voice system, businesses not only reduce
CapEx and OpEx expenses but they also improve employee produc-
tivity. Information flows more quickly throughout the organization.
With UC, communication modality can evolve immediately. Communi-
cation is streamlined, data transfers are enhanced, and video confer-
encing becomes more common. Instead of listening to an audio call,
retrieving a presentation from email, and having to reserve the video
conferencing room an employee can use UC to engage in a multiple
point video conference from their desk that includes the ability to
share content.
In fact, many businesses reduce airplane travel by 10% or more, so rather
than sitting on a plane and traveling to and from New York and San Jose,
employees spend those 10 hours in the office, collaborating with their
coworkers. “One of our customers wanted to use the conferencing capa-
bilities within Lync to reduce its travel expenses by 10%; but because Lync
was so simple to use, they reduced it by nearly 90%,” which amounted to
significant cost savings, adds Modality Systems’ Rodd.
Yet few companies are fully reaping the potential benefits. Right
now, Nemertes estimates that only 11% of businesses are replacing
or planning to replace their PBXs with Lync for telephony; most are
only using Lync for instant messaging, according to Lazar. To fully
take advantage of Lync Enterprise Voice functionality, a corporation
needs a robust SBC, which acts like a network “Swiss Army Knife”
ensuring that everything works together seamlessly. Key features
found in the best SBCs are reliability, integration with old and new
networking solutions, integrated dial plan and policy management,
and strong security.

In early 2012, Sonus found itself in a predicament faced by many businesses.
A series of acquisitions and expansion by various departments had left it with
a network hodgepodge. The network equipment supplier had 1,100 employees
stationed in nine offices spread out on three continents. The employees used a
variety of communication and collaboration systems, but a more cohesive network
infrastructure was needed.
In the summer of 2012, Sonus CIO Bill Scudder and his team pushed a company-
wide migration to Microsoft’s Lync system to the top of the IT priority list. Time was
of the essence. The firm decided to move all employees to Lync messaging, video,
and voice functions in eight weeks.
An upgrade to the Sonus enterprise network took about six more months. As
part of that change, Sonus consolidated its network infrastructure: replacing
legacy PSTN and VoIP gateways at each office with a single Sonus Session Border
Controller branch appliance.
Sonus also integrated the Microsoft solution with key business applications, such as
Salesforce.com and Microsoft Exchange. The enhanced communication and collabo-
ration among colleagues provided employees with several benefits:
Click-to-call from their IM or email screen whenever they see a coworker
is available
Host interactive whiteboarding sessions with cohorts from around
the world
Set up an audio or video conference for up to 200 people in less than
60 seconds
Share their desktops with remote technical support specialists for faster
problem resolution
In April 2013, the upgrade was completed, and workers became more productive.
When impediments like snowstorms prevent employees from reaching the office,
more work rather than less is completed because individuals still collaborate with
their colleagues. In the first full month after the companywide rollout of Lync, the
number of internally hosted video conferences rose by nearly 50%. Perhaps most
important, Sonus has already seen a nearly 200% ROI from the following cost
reductions:
$40,000 savings per office by replacing multiple voice gateways with a single
SBC
$150,000 per year savings in operational expenses by simplifying/unifying
network administration on a single communications platform (Lync)
$200,000 per year savings by internally hosting telecom services on the Lync
Server and using the SIP-based wide area network to route long-distance calls
Many businesses find themselves in similar positions to Sonus: running their busi-
ness on a less than optimally designed network. Taking the time to upgrade to
a modern UC solution, SIP, and SBC based network offers them the potential to
dramatically reduce their operating costs as well as significantly boost employee
productivity.

DEPLOY A RELIABLE
NETWORK INFRASTRUCTURE
TO PERFORM WELL AND ENABLE their businesses to succeed,
employees need to exchange information quickly and easily. As a
result, business performance has become closely tied to network
availability: indeed, wide area network (WAN) outages can cost busi-
nesses hundreds of thousands of dollars per incident.
Businesses cannot afford any network interruptions; they are simply
too disruptive and expensive. In the airline industry for instance,
carriers rely on their networks to book flights and convey information
to passengers. In late September 2010, the check-in and online booking
systems of Australian airline Virgin Blue (now Virgin Australia) began
suffering intermittent downtime. Then a hardware failure on September
26 brought down the airline’s Internet booking, reservations, check-in
and boarding systems. The outage severely disrupted Virgin Blue’s busi-
ness, affecting around 50,000 passengers and 400 flights, before order
was restored in early October. Virgin Blue had outsourced maintenance
of its reservation system to Navitaire, an airline reservation specialist;
Virgin Blue estimated the cost of the outage at $20 million.
However, there are limitations with existing enterprise voice system
designs. The most obvious is vulnerability: they feature two critical
points of failure. With TDM trunking, companies operate a single,
physical connection between themselves and their service providers.
If something happens to that connection, the service goes down, and
all users are left without network access. Even with an IP-PBX and
SIP trunking, a company still has a central point of failure. All of the
system intelligence is confined to the data center. If a problem arises
there or on a link from it to a remote branch, then all of the employees
are knocked offline and there is no way for anyone to communicate.
In markets like financial services, healthcare, and oil and gas, such
outages are catastrophic.
To date, adding needed redundancy has left companies with three
mainly untenable options:
1. First, companies could duplicate the systems configurations:
This approach is often impractical because of very high CapEx.
2.Companies could put fully redundant lines in place. With SIP,
calls are routed over any portion of a firm’s IP bandwidth. If a
link goes down in one location, data is sent via other IP connec-
tions. But this approach is OpEx intensive. Technicians need to
manually enter data and track network changes.
3.Put network appliances in each location: This melding of the
first two options is not a panacea because it can still be costly
and difficult to maintain if the correct appliance is not chosen.
The best option is Lync, SIP and the right SBC. With this design,
companies reduce network device complexity because minimal
hardware elements (true appliances rather than servers) are
stationed at remote locations. This approach offers flexibility: it
supports 3G or 4G wireless connections as well as local switching.
This alternative is reliable: the system automatically routes calls if
hardware or WAN problems arise. Lync, SIP and the right SBC add
the resiliency needed with today’s enterprise networks.

Microsoft Lync is clearly outperforming the competition, according to
market research firm Synergy Group. The company found that in 2012
worldwide revenues for enterprise IP telephony fell by more than 6%,
but Microsoft’s revenue in the segment grew by more than 40%.
So what is behind the seemingly antithetical numbers? First, the
design of the Microsoft solution fits well with emerging commu-
nication system design. These functions are shifting from a voice
only design to support for multimedia communications. Because it
supports a variety of communication options (voice, video, email,
instant messaging) Lync meshes well with the growing business need
to run sophisticated voice applications, such as contact centers and
unified communications. “With Lync, businesses are able to dramati-
cally change the corporate culture and how employees collaborate,”
MICROSOFT LYNC
GAINS SUPPORTERS
says James Rodd, Co-Founder and Managing Director at Modality
Systems, a Unified Communications specialist.
Second, Microsoft offers robust integration with existing enter-
prise business systems. Many companies run their business on
products like Windows, Exchange, SharePoint, and Microsoft
Office. “Lync offers strong connectivity to Microsoft business
solutions,” states Irwin Lazar, Vice President and Service Director
for Nemertes Research Group, Inc.
Microsoft has also done well extending its communications
options. Lync includes robust voice functions, but it also stacks up
well against leading instant message and presence solutions. The
Microsoft Lync voice system works well with social networking
products.
For Microsoft, the best is yet to come. “Microsoft is poised to gain
more momentum in enterprise voice communications market,”
concludes Nemertes’ Lazar.

SOOTHE MIGRATION PAIN POINTS
ENTERPRISES TODAY ARE RESPONDING to new competitive
challenges and starting to deploy modern applications; however,
many can be hampered by outdated network infrastructures. They
need a networking solution that will enable them to migrate from an
out-of-date network to a modern SIP infrastructure.
Implement Enterprise Voice while retaining some or all of the IP-PBX
infrastructure. In some cases, this will be to leverage the TDM
telephony interfaces offered by the IP-PBX, while in other cases, the
IP-PBX will stay in service to provide specific services or to serve
some segments of the network while others are transitioned to Enter-
prise Voice.
The SBC plays a vital intermediation role and can provide SIP normal-
ization, transcoding, and transrating to allow a smooth integration
between Enterprise Voice and the IP-PBX. Most larger enterprises
have a disparate IP-PBX base—more than one vendor serving the
company with different IP-PBXs in different locations. In these cases,
an SBC is even more vital to a smooth integration because it’s likely
that each of these different IP-PBXs will have its own SIP variations
and transcoding requirements.
However, communications system upgrades must be carried out
without risking downtime. Rip and replace is out of the question.
What’s more, employees resist change. They prefer to continue
working with an old system rather than learn how to use a new one.
Consequently, businesses need to invest time, effort, and money into
educating employees about the benefits of a new system. Also, voice
systems are large and complex, so moving to a new one takes time.
As a result, enterprises need a new voice infrastructure that:
Works with existing as well as new handsets
Is compatible with legacy equipment: Fax numbers, call center
ACDs, and paging systems
Supports enhanced services, like E911
Works with Microsoft’s Active Directory for a smooth migration
In addition to the SIP normalization and transcoding/rating functions,
SBCs also serve to provide a centralized call routing intelligence —
located logically “above” both the IP-PBXs and the Lync Enterprise
Voice servers. So the SBC can be the brains of the deployment,
helping to ensure that calls are routed correctly, with the most effi-
cient use of network resources and the lowest costs.
In sum, movement to a new network infrastructure is a complex
process. In many enterprises, migrating to a new system takes two
to three years. Because of this, businesses demand enterprise voice
solutions that coexist with the old system as employees begin to take
advantage of the new one.

CLOSE NEW SECURITY HOLES
HISTORICALLY, IT MANAGERS have not lost sleep worrying about
TDM security: these lines were not open to intrusion. Instead, the
migration from legacy TDM to VoIP networks makes their nights much
more restless. With IP-based voice communications, they open them-
selves up to malware, worms, and man-in-the-middle attacks. In fact,
SIP-sniffing software is readily available to criminals on the Internet.
For enterprises, the security stakes are quite high. Lync Enterprise
Voice network operators—both enterprises and service providers—
face threats to the security of their network and business in addition
to the everyday issues such as how to make VoIP work seamlessly
and efficiently while also realizing the cost and bandwidth savings that
VoIP promises.
Some of the common attacks enterprise and service providers face are:
DENIAL OF SERVICE (DOS) ATTACKS: Outside attempts to over-
whelm the network with fake connections
SPOOFING ATTACKS: Nefarious users attempt to gain access to
the network deceptively
TOLL FRAUD: Hackers attempt to access the network in order to
route calls over it at the network owner’s expense
To address the problem, companies should no longer link IP trunks
directly to a PBX. Instead, they should terminate trunks at a SIP-
capable SBC, which acts as a firewall. Unlike a TDM line, a SIP system
prohibits persons from simply plugging in and making calls. Trunks
are provisioned only after users are authenticated. During a recent
webinar, Nemertes revealed the top three productivity trends in UC
and cited increased security as the number one reason why enter-
prises are deploying an SBC.
The SBC controls the admission of calls in and out of the enterprise
and protects the network against denial of service (DoS) attacks, toll
fraud, and other attacks against the Lync Enterprise Voice network.
Additionally, the SBC can “hide” the topology of the Lync network
within the enterprise, so external parties aren’t able to detect the
devices within.
The Path
Forward
The use of Lync
Enterprise Voice
is becoming more
common in busi-
nesses because
the technology
offers firms a way
to cut costs and
improve produc-
tivity. However,
enterprises need
to deploy this system in a way that offers them reliability, a sound
migration path, and security. To do this, they should combine the
Lync system with a state-of-the-art SBC.

SESSION BORDER CONTROLLERS play a critical role in acceler-
ating Microsoft Lync deployments. Too often, enterprises get delayed
because of unforeseen or unplanned challenges. So, how do enter-
prises ensure a quick and successful Lync deployment?
A few simple steps–and considerations–can help move your Lync
deployment forward, easily and reliably.
#1 Plan Ahead
Most Lync deployments begin with instant messaging (IM) and pres-
ence, which is the logical first step.
Once the infrastructure necessary for IM and presence is deployed,
enterprises also have the ability to do peer-to-peer voice and video.
However, existing voice communication infrastructure (consisting of
IP and legacy PBXs as well as PSTN trunks) is often a separate “voice
island” that doesn’t interoperate well with Lync.
Unified Communications is about having single identity reach, regard-
less of the device or user application, whether a desk phone, a mobile
phone or even a smartphone application. Disparate “voice islands”
create just the opposite–separation, not unification. Most enterprises
also won’t retire existing infrastructure immediately at the onset of
3 TIPS FOR MOVING YOUR
LYNC DEPLOYMENT FORWARD
Lync deployment, which means a mix of old and new in the network.
Many enterprises will move from PSTN trunks to SIP trunking (if not
doing so already) to take advantage of new features like high-definition
(HD) voice and video and enable Cloud communications, but the move
will be at their own pace.
Without planning ahead, enterprises that start a Lync pilot with IM and
presence may get stuck in the pilot phase indefinitely when they come

®
across these “new requirements” for voice deployment. They need a
way to migrate to Lync seamlessly with ease.
#2 Remember: It is always an interworking
and survivability story
Enterprises need to consider how to bridge voice islands because
more often than not, it will be a migration story from existing to new
technologies. Interworking is the key to make it work together. And
interworking is an even bigger requirement when enterprises are
planning to deploy (or will deploy) SIP trunks in an environment with
both Lync and legacy equipment. Many enterprises underestimate the
amount of analog devices in their network that need to interoperate
with the new technology. Fax machines, common area phones,
paging systems, etc., all need to be planned into an enterprise’s Lync
migration to ensure a seamless, successful deployment.
Enterprises also need a business continuity plan in the event of a
network outage. This is especially critical for enterprises with branch
ofﬁces. If the wide area network (WAN) goes down, enterprises need to
ensure communication and connectivity between the corporate head-
quarters and remote locations. They also need to ensure that enterprise
branches are able to make calls out to 911 during emergencies even
during WAN outage.
#3 Think Session Border Controller
How can enterprises ensure quick and successful Lync deploy-
ment amidst the challenges? The answer is simpler than you may
imagine; it’s a Session Border Controller (SBC).
The SBC is a device that sits at the border between the internal
Lync Enterprise Voice network and the SIP trunk service provided by
the Internet service provider (ISP) or a legacy Internet protocol (IP)
telephony infrastructure, providing a host of security, service enable-
ment, and control functions for any VoIP or UC network. The SBC—
which Microsoft recommends be included in a Lync Enterprise Voice
Deployment to ensure interoperability and functionality— provides
interworking across different protocols, dial plans and media types
to enable that migration story to be realized by enterprises while also
ensuring security, connectivity, interoperability and survivability.
The SBC provides interworking across different
protocols, dial plans and media types to enable
that migration story to be realized by enterprises
while also ensuring security, connectivity,
interoperability and survivability.

AN ENCOUNTER WITH A LYNC MASTER is a rare experience.
There are only about 100 of them on the planet and most of them work
for Microsoft. The Lync Master Certification process starts by winnowing
out all but the top Lync specialists, and then it gets serious. Should
candidates get past the grueling interview process, they will be invited
to Redmond for an intensive 3-week certification program, where the
world’s leading Lync experts will cram years of information into your
brain. Then comes the real work: a two-part written and lab exam that
only one in three students will pass to become a certified master.
Most systems integrators would love to have one Lync Master
on staff. ExtraTeam has four. That’s right. In a company with 50
employees, you can’t swing a Polycom phone at either of ExtraTeam’s
coastal offices without hitting someone who knows a boatload about
Lync. ExtraTeam’s Director of Engineering and longest-standing Lync
Master Mike Sneeringer has some words of advice that can connect
you to a higher consciousness of Lync.
Prepare. According to Lync Master Mike, communication is only as
strong as the network that supports it. “Have a network assessment
done to accurately identify potential problems and challenges before
you start to implement Lync. Businesses first need to make sure their
network has sufficient bandwidth, security and the right quality of
service (QoS) policies to support a unified communications solution.”
Partner. For UC to work, everything needs to work together: Lync
servers, gateways, phones, legacy applications. “You want to work with
5 WORDS OF WISDOM FROM
A ZEN LYNC MASTER
a systems integrator who can
not only get all of the pieces to
play together,” says Sneeringer,
“but also knows how to exploit
all of Lync’s features to give you the best possible experience.”
Equip. It’s one of the most common mistakes that Sneeringer and
his ExtraTeam mates see: companies that fail to realize the full potential
of Lync because they don’t invest in the right equipment. As Mike
explains it, “Companies won’t get optimal voice and video from Lync
unless they also invest in certified phones, headsets and cameras.”
Simplify. Unifying communications isn’t as simple as SIP
trunking. “Different vendors implement SIP in their products
differently,” Mike cautions, “so you need a Session Border Controller
to provide the interoperability between telephony services.
Otherwise, something like music on hold might not work with Lync.
That’s why we recommend Lync-certified SBCs. They’ll ultimately
speed up your deployment and you’ll spend less time on the phone
with tech support.”
Train. According to Master Mike, training is the first step to
success. “Companies need to make sure that employees have
access to training right from the beginning, whether in person or
over the Web. If you can deliver a positive experience to users right
in the beginning, they’ll embrace it and you’ll start to see those
productivity gains almost immediately.”

The SBC plays a big role in a Lync Enterprise Voice deployment; it sits on
the edge of the network and provides all sorts of security and mediation
services to keep things running smoothly. It communicates between two
network end devices, such as a Lync SIP VoIP call between two phones.
These communications are called SIP sessions. Because of where the SBC
fits in the network, it can be usefully implemented by both businesses
themselves and also by the service providers who serve them. Take note
of these key criteria when considering an SBC for your UC deployment.
1. WIDE-RANGING MEDIA SUPPORT
Sonus SBCs provide a wide range of support for different media types
because they don’t rely on off-the-shelf solutions (with generic off-the-
shelf software) for media processing. Instead, Sonus creates its own
firmware, which allows Sonus to responsively add additional media types
as needed without waiting for a vendor to come along with a solution.
2. MULTIVENDOR INTEROPERABILITY
Sonus SBCs are deployed throughout the world in a variety of environ-
ments, supporting Lync Enterprise Voice and a wide range of IP-PBXs and
legacy TDM-PBX systems in different configurations.
3. RESILIENCY AND PROTECTION AGAINST ATTACKS
Sonus SBCs offer sophisticated real-time firewalling and the use of tech-
niques such as Virtual LAN (VLAN) tagging, which drops the malicious
packets and allows legitimate traffic to continue on to the network unim-
peded. So the enterprise stays online and productive!
4. ENCRYPTED COMMUNICATIONS
With a Sonus SBC and its support for AES encryption (128 bit), potential
eavesdroppers aren’t able to make head or tail of a conversation they
might be able to otherwise listen in on.
5. RAPID RECOVERY
Sonus SBCs are built to make the disruption of an outage a minor
Finding the Right SBC for Your Lync Deployment: Things to Look For
rather than a major event. If a failure occurs, the Sonus SBC automati-
cally attempts to find alternate routes to complete calls without the
end-user ever knowing that there’s a problem. In branch sites, the
Sonus SBC can automatically reroute calls to the PSTN when the
IP network goes down, giving the user the service needed without
disruption.
6. SURVIVABILITY FOR BRANCH SITES
Sonus SBCs include full support for Lync SBA. In fact, Sonus takes this
one step further and supports full Lync Enhanced SBA with 3G/4G
failover capability. So an enterprise’s branch sites get high-quality voice
services, ready-to-go survivability and require one less device in the
network—that makes the network simpler and cheaper to provision and
manage.
7. CENTRALIZED POLICY MANAGEMENT
Sonus SBCs can be centrally managed. Whether an enterprise (or service
provider) needs two SBCs or 20, a single set of policies and configurations
can be established one time and sent to all locations with one action,
which means lower expenses for IT and better/faster results for users.
This streamlining also eliminates the need to hire IT technologists to main-
tain and update policies.
8. EXCEPTIONAL TRANSCODING PERFORMANCE
Often voice calls aren’t in the same codec, such as when in languages
a translator or in UC a transcoder is needed to convert between the
two. The Sonus SBC platform has a separate processing architecture of
media transcoding and transrating, so the overall performance of the
SBC doesn’t take a “hit” when a lot of processor-intensive transcoding is
going on.
9. MICROSOFT COMPATIBILITY AND QUALIFICATION
Sonus is a qualified Microsoft Lync hardware partner and has several
models of SBCs qualified for use in a Lync Enterprise Voice environment.
Sonus is a global leader in
IP networking with proven
expertise in delivering se-
cure, reliable and scalable
next-generation infra-
structure and subscriber
solutions. Sonus has the
broadest portfolio of Micro-
soft Lync qualified Session
Border Controllers (SBCs),
providing the industry's
only end-to-end portfolio
to deliver SIP-enabled ap-
plications from the branch
office to the central office.
