  1. The leader in session border control for trusted, first class interactive communications

  2. SIP trunking & enterprise SBCs

  3. SIP Trunking 2008-2013 CAGR of 91% Session Border Controller 2008-2013 CAGR of 49% Positive outlook for SIP trunking and SBCs through 2013 • Still in early stages • CY08, $130M in revenue, 208.5K SIP trunks • North America driving SIP trunking • 74% total trunk shipments in CY08 • Two dominant SBC players – Acme Packet and Cisco Systems • 68% of enterprise SBC revenue from NA in 2008 Infonetics: June 2009

  4. Acme Packet is leader in delivering SIP trunking services • SIP trunking availability from APKT service providers exploding • 80 deployments and trials today • 30 countries • Many different IP PBX/UC environments supported • APKT in service provider network + APKT in enterprise network= guaranteed interoperability and faster time-to-trunk • Same border controls for service provider & enterprise • Security • SLA assurance • Service reach/interoperability • All IP trunking protocols supported – RFC 3261 SIP, SIP-I, SIP-T and H.323

  5. Why do you need an enterprise SBC? • Many PBX and UC vendors have SIP interfaces or other methods for connecting PBX and UC elements to a carrier SIP trunk service • This causes some enterprise telephony and UC managers to ask: • If my PBX or UC platform supports a native SIP trunk interface, why can’t I just connect this interface directly to the carrier SIP trunk service? • 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? • How is the Acme Packet solution packaged?

  7. SIPconnect - enterprise SIP trunking profile accelerates time-to-trunk SIP Forum spec ratified August 2006, now V1.13 Specifies RFCs that must be supported for SIP trunking SIP, TCP, TLS, RFC 4733 DTMF, G.711 20ms, E.164 & URI addresses, SIP server discovery, response codes, IPv4 addresses SIP RFC 3261 Media G.711, 20ms TLS Service provider Enterprise PSTN

  8. SBCs assure service availability & quality Session admission control – signaling element, network, user Signaling-based – number of call /sessions, signaling rates Media (bandwidth)-based Overload control Non-malicious – load balancing, SIP registration avalanches, mass calling rejection/diversion Malicious Failure detection & recovery - data center redundancy, remote site survivavbility L3 router IP PBX or UC server Service provider SIP trunk/SBC Transport control Packet marking and mapping Media release peer-peer Quality of Experience (QoE) QoS & ASR monitoring, reporting & routing IP PBX UC SIP Nomadic/ mobile user HQ/ campus Remote site Remote site Tele-worker 2.

  9. SBCs enable regulatory compliance Call and session recording Replicate session (signaling and media) for recording Session privacy Secure signaling and/or media Emergency calls E-9-1-1 Retrieve location information, add to signaling Route based upon location Prioritize routing (SIP RPH) & IP transport Exempt from admission control polices 1.

  11. Why use SBC for enterprises & contact centers? Real-time IP communications is different Sessions initiated from inside or outside of firewall Continuous stream vs. traffic bursts, 2-way flows Latency & jitter very important, loss not so important Security is paramount Multi-protocol and real-time nature of VoIP demands sophisticated stateful defense strategy Signaling overloads occur with network outages, attacks simple to launch Today’s firewalls are insufficient, unable to: Protect themselves or IP PBX/UC resources Open / close RTP media ports in sync with SIP signaling Perform VoIP signaling deep packet inspection Track session state and provide uninterrupted service upon failure Enable VoIP interoperability for all layers/protocols SBCs deliver more than security using back-to-back user agent approach vs. ALG Service reach maximization SLA assurance Regulatory compliance Cost control

  12. SBC (B2BUA) Terminates, re-initiates and initiates signaling & SDP Two sessions - one on each side of system Layer 2-7 state aware Inspects and modifies any application layer header info (SIP, SDP, etc.) Static & dynamic ACLs Firewall with SIP ALG Summary comparison:SBC vs. firewall with SIP ALGs SIP trunk SIP trunk Data center Data center IP PBXUC server IP PBXUC server • Unable to terminate, initiate, re-initiate signaling & SDP • Single session across system • Layer 2-4 state aware • Inspects and modifies only application layer addresses (SIP, SDP, etc.) • Static ACLs only 12 Acme Packet

  13. Why use SBC for enterprises & contact centers? • Real-time IP communications is different • Sessions initiated from inside or outside of firewall • Continuous stream vs. traffic bursts • 2-way flows • Security is paramount • Multi-protocol and real-time nature of VoIP demands sophisticated stateful defense strategy • Signaling attacks are simplest to launch • Today’s data focused solutions are not enough • Lack ability to dynamically correct VoIP connectivity issues • Unable to perform VoIP signaling/media deep packet inspection • Inability to track session state and provide uninterrupted service • Firewalls and routers cannot protect UC resources • Back-to-back user agent proven superior to ALG • SBCs deliver more than security • Service reach maximization • SLA assurance • Cost optimization

  14. SBC vs. alternative approaches
