  4. 4. Market Overview
  5. 5. SIP Trunking Trends SIP Trunking still in early stages CY08, $130M in revenue, 208,000 SIP trunks North America leads deployment Driven by cost EMEA market more fragmented, but growing rapidly Large number of providers emerging Characterised by value – not price NA APAC 12% 21% APKT service provider customers CALA lead the way 26% 80 deployments and trials today EMEA 30 countries 41% Many different IP PBX/UC environments supported
  6. 6. SIP Trunking - Benefits Improved network efficiency to control and reduce costs Consolidate traffic from small remote sites Economies of scale, remove need for PSTN access at each remote branch Leverage IP technologies for operational efficiency gains SIP VoIP becomes just another overlay application Lower operational costs Eliminate TDM gateways Improved bandwidth utilisation = fewer circuits for the same number of calls Improve voice quality Eliminate unnecessary IP-to-TDM-to-IP translations and associated latency Exploiting high fidelity IP codecs Deploy new applications to increase efficiency Simplifies integration with hosted servicesThe time is now – In the current economy cost savings are critical
  7. 7. What is an SBC?
  8. 8. SBCs overcome UC obstacles Secure the borders of a VoIP or UC network Protect VoIP video and UC , sessions Fix protocol interworking issues Bridge incompatible systems Connect remote workers easily and securely Alternative to VPN Tunnels Assure and measure session quality Disaster recovery and survivability Support regulatory compliance Enable call recording, call privacy, functional segregation
  9. 9. SBCs overcome UC obstaclesOn premise Hybrid Hosted/Centrex
  10. 10. SBC Applications
  11. 11. When do customers need an SBC? SIP trunking SBCs essential for security, interoperability, SLA management, diverse routing Remote worker Security, encryption, NAT traversal, QoS control Branch office connections Protocol interworking, QoS control, encryption termination, overlapping IP addressing schemes Hosted services e.g. contact centre, Microsoft OCS SBCs essential for security, interoperability, SLA management, diverse routing Enterprise FMC Security, encryption, topology hiding, NAT traversal
  12. 12. Direct connect deployment model Many PBX and UC vendors have SIP interfaces or other methods for connecting PBX and UC elements to a carrier SIP trunk service So Enterprise telephony managers ask: Why can’t I just connect this interface directly to the carrier SIP trunk service?
  13. 13. Why do you need an enterprise SBC forSIP Trunking? This presentation will address this question and others such as: Why do I need an enterprise SBC for SIP trunking interoperability? Why do I need an enterprise SBC for SIP trunking security? Why do I need an enterprise SBC for SIP trunking control? How does using an enterprise SBC enhance my disaster recovery, troubleshooting, and monitoring capabilities? “Enterprise SBC” Reference Model (PBX* connects to Service Provider SBC via Enterprise SBC)
  14. 14. An enterprise SBC helps with SIPtrunking interoperability PBXs may not interwork directly to carrier SIP trunks due to differences in SIP implementations or when H.323 is the only available IP interface Acme Packet solves this problem by providing: Complete SIP header manipulation rule (HMR) capabilities to interwork different SIP dialects between PBX and carrier SIP trunking elements Full H.323 – SIP interworking Media transcoding & DTMF format (INFO / 2833) interworking Signaling transport (UDP / TCP / TLS) and media encryption (RTP/SRTP) interworking These capabilities enable virtually any SIP or H.323 capable PBX or UC platform to talk to any carrier SIP trunk service Proven interoperability with all of the major PBX and UC vendors
  15. 15. An enterprise SBC helps with SIP trunksecurity The VOIP Firewall Enterprise Security Managers will not connect to public data networks without a firewall on their premises They won’t connect to public VoIP services without an SBC Enterprise SBCs fit into the “Defence in Depth” model for IP security The Enterprise SBC provides complete topology hiding and DoS protection of SIP signaling and media traffic for the Enterprise Just like Application Layer Gateways (ALG) used for other enterprise IT applications today Features include dynamic port control, dynamic trust management, encryption and overload protection Service Providers use SBCs to protect their network – enterprises should do the same
  16. 16. An enterprise SBC helps with SIP trunkcontrol In the simplest model, the enterprise SBC routes inbound and outbound calls between the PBX and the carrier SIP trunk via static dial plans Many enterprises use SBCs for more advanced routing and control scenarios including: Least cost routing, call quality-based routing, time-of-date routing Connection Admission Control (CAC) Failover & load-balancing routing Called & calling number digit normalization Routing Decisions Can Be Based On: Called or Called Party Number (or any field in the SIP header) Cost metrics, Time-of-day, CAC loads Media codec or type (voice vs. video) PBX or carrier trunk availability Call quality requirements (best effort or high MOS score)
  17. 17. An enterprise SBC helps with disasterrecovery Some enterprises are moving to SIP trunks for improved network resiliency in disaster recovery (DR) scenarios The enterprise SBC plays a key role in a DR architecture with support for the following capabilities: 1+1 High Availability clustering between SBC elements Signaling and media state preserved in the event of a failover Automatic detection and reroute around failed PBX or carrier links No operator intervention or PBX reconfiguration required
  18. 18. An enterprise SBC helps with SIP trunk troubleshooting A challenge for many enterprise telephony managers is to how to apply traditional TDM troubleshooting methods to SIP trunks The enterprise SBC helps by providing an embedded probe that allows you to monitor all SIP & H.323 signaling and media traffic Provides full signaling traces, ladder diagrams, and media statistics Information is automatically collected and can be retrieved via EMS and can be sorted based on calling or called party number, SIP call ID, time-of-call, etc. An embedded call recording utility is also provided EMS allows partitioned access to control who can view what information Statistics = Media Quality Stats with MOS, packet loss, etc.Call Diagram = Ladder Diagram & Detailed Message Trace Play = Bi-directional Media Recording Capability (on-platform Session Replication for Recording (SRR))
