Microsoft Lync is the leading Unified Communications (UC) platform in the marketplace today - seamlessly combining telephony, instant messaging, web conferencing, and A/V conferencing in a single application. But organizations are struggling with the question of how to make Lync work with their existing investments in legacy Cisco IP telephony. In this session, we will be taking a deep look at the best ways to leverage Lync in addition to an existing Cisco infrastructure. Based on years of integration experience with Microsoft UC and Cisco, Perficient will share best practices and recommendations for getting the most out of Lync. This event will give you clear ideas of what works, what doesn't, and how best to bring UC to your organization.

10. 3 Lync/Cisco Integrations
10

11. The 4th and Best Way
Lync is the application, Cisco is the network!
11

12. Deciding How to Integrate
Define Your Requirements
Which users need which functions?
How do people actually work together?
Use the Best Tool for the Job
Sometimes IP phones on desks are good enough
Just because you’ve always used a technology doesn’t mean it’s
the best
Segment User Populations
Different sites have different needs
Mobile workers, sales force, knowledge workers are require
different functionality
12

13. 3 Ways to Integrate
SIP: Trunk or Gateway
CUCM 5.x and up supports “Direct” SIP
You may still want a gateway, depending on your situation
Remote Call Control
Using Lync client for IM, Presence
“Click-to-Call” takes your Cisco phone off-hook
Client Side Plug-in
CUCiLync
It’s bad, what can I say?
13

14. Lync With Client-Side Plug-in
14

15. Lync With Client-Side Plug-in
It’s a Cisco softphone bolted on to your Lync Client
It registers with Call Manager
What It Is
It gives you softphone and Lync
Pros
Cons
It’s difficult to manage
It’s confusing for end-users
It’s expensive
You need a VPN
15

16. Lync With Remote Call Control
16

17. Lync With Remote Call Control
It’s a Cisco Presence Server integrated to both Lync and
Call Manager
What It Is
Gives you “click to call”
Gives you “phone presence”
Pros
Cons
It’s difficult to manage
It’s confusing for end-users
It’s expensive
You need a VPN

18. Lync With Direct SIP
18

19. Lync With Gateway Upstream
19

20. Lync With Direct SIP
You can send calls back and forth
What It Is
Pros
Allows users to use Lync as a softphone
Allows you to use Lync as a conference bridge
Is well supported by Cisco & Microsoft
Clean lines of delineation: Microsoft on the desktop / Cisco as
a handset
No “phone presence”
Cons
20

21. Lync With Direct SIP
It uses G711
It uses TCP
It uses the SIP standard, but…
It has to be certified by MS
You can register generic SIP phones, but…
21

22. Lync With Direct SIP – Why to Do it
Let remote users use Lync for softphone
•
Ditto for traveling users
•
Ditto for hoteling users
•
Ditto for people who don’t like expensive, clunky handsets
Convert a single branch office
Keep PBX handsets, use Lync for everything else, especially
conferencing
Replace handsets over time
22

23. Lync With Direct SIP – How to Wreck it
We don’t need a plan, we’ll figure it out”
“I want my PBX phone to ring AND Lync to ring!”
•
It can be done.
•
That doesn’t mean it should be done.
•
Not fun setup in the PBX to fork calls.
•
Voicemail, etc. – It can be a problem.
•
Just use a Lync phone if you want this scenario (easy for me to
say).
But, yes, it can be done.
Golden Rule: Do Not Deploy the Same Service (Voice) to
the Same User on Two Different Systems.
23

24. Lync With Direct SIP – How to Wreck it
“I have 50 branch locations, can I tie
into just 1 Lync server back in HQ?”
•
It can be done.
•
That doesn’t mean it should be done.
•
This causes WAN hilarity.
•
You really need to decide how you want
Lync to work for you.

25. Lync With Direct SIP – Easy Dial Plan
One Main Step in Lync: *.
• Create the trunks
• Create the route groups
• Create the route list
• Create the route patterns (88.XXXX)
• Forward the DNs
• Route the calls
• Serves 1-1000 users. Enjoy!

26. Lync With Direct SIP – Easy Dial Plan
To Be Considered:
• QoS
• CAC
• MTPs
• Bandwidth Usage
• Codecs / Transcoding
