  1. SIP Trunking… Why is it so important?

  2. Typical IP PBX Components Enterprise PBX PSTN Enterprise Media Gateway IP Telephone TDM IP • Today: • IP PBX Capabilities Deployed INSIDE the Enterprise • Hardware gateways connect traditional voice circuits

  3. Carrier Softswitch Enterprise Softswitch Carrier IP Infrastructure PSTN PSTN Enterprise Media Gateway IP Telephone Carrier Media Gateway CLASS Switch Carrier Media Gateway TDM TDM IP IP Carrier Softswitch Enterprise Softswitch Carrier IP Infrastructure PSTN IAD IP Telephone Carrier Media Gateway TDM IP TDM IP IP to TDM to IP to TDM … TODAY… AN INTERIM SOLUTION…

  4. Carrier Softswitch Enterprise Softswitch Carrier IP Infrastructure PSTN PSTN Enterprise Media Gateway IP Telephone Carrier Media Gateway CLASS Switch Carrier Media Gateway TDM TDM IP IP Carrier Softswitch Enterprise Softswitch Carrier IP Infrastructure PSTN Enterprise Edge IP Telephone Carrier Media Gateway TDM IP IP to TDM to IP to TDM … TODAY… NOW…

  5. Carrier Softswitch Enterprise Softswitch Carrier IP Infrastructure PSTN Enterprise Edge IP Telephone Carrier Media Gateway TDM IP This is Real SIP Trunking. • Pure IP voice connectivity = Better Quality • Flexible number of voice calls = Business Flexibility • Less hardware devices to manage = Lower Costs • Single circuit with multiple services = Better Economics

  6. Multi-carrier terminations… A Carrier Softswitch Enterprise Softswitch PSTN • Call-by-call termination leverages cost benefits of multiple carriers & improves performance • Multiple IP termination points across enterprise provide inherent redundant paths • Multiple carriers inherently provide greater reach Carrier Media Gateway B PSTN Carrier Media Gateway Carrier IP Infrastructure C Enterprise Edge PSTN IP Telephone Carrier Media Gateway TDM IP

  7. Voice over “Managed” IP Best Efforts Voice Quality, Capacity Controlled Un-Managed VoIP Gateway Trunking Comparison of Service ModelsConsumer & Business Business Large Medium Small Consumer / Residential Market Segments Business Models Voice: (Local+LD+Toll Free), Data, Web Hosting Bundled Services (Triple Play) Cheap Dial Tone Internet Dial Tone Service Models Fully Managed Service Level Agreements, performance + fault monitoring, QoS, etc. Service Types SIP “Soft” Trunking VoIP Centrex ITSP Examples AT&T, BandTel, Cbeyond, Global Crossing, Starvox, USLEC, XO . . . Comcast, Vonage, Tomato Vine. . .

  8. Comparing Service Types Type Description Pro Con • Providing managed telephone service to a business over an IP connection. • This may be wither a “fully managed” or “un-managed” IP connection. • Full service • No expert staff needed • Low initial investment • Little to no “control” • Restricted Capabilities VoIP Centrex • Providing voice and data services to a business over a “converged” network connection. • Narrowband Voice Services are broken out separately at the customer premise using a “media gateway”. • Economics of V+D convergence • Narrowband service – limited services • Personnel costs • CapEx VoIP Gateway Trunking • Providing broadband voice and data services to a business over a “converged” network connection. • Voice services are broadband or “all IP” to the telephony device. • Economics convergence • Enhanced Services • Lowers CapEx • Personnel costs (compared to VoIP centrex) SIP “Soft” Trunking

  9. Understanding the SIP Trunk Services • Managed vs. Un-managed (Device Management) • On-net vs. Off-net (TDM points/IAD, Carrier hop-off) • Quality of Service Capabilities (V quality methods) • Service Level Guarantees (Contractual Warrants)

  10. THERE’S MORE… …that makes SIP Trunking important.

  11. Carrier Softswitch Enterprise Softswitch Carrier IP Infrastructure PSTN Enterprise Edge IP Telephone Carrier Media Gateway TDM IP Once you’re IP, More opportunities… • The enterprise IP PBX has become a software-based unified communications engine • Easily downloaded, and installed on standard servers • It offers much more than just voice over IP! • How can you leverage IM, Video, Presence and more?

  12. Carrier Softswitch Enterprise Softswitch Enterprise Softswitch TDM Telephone Carrier IP Infrastructure PSTN PSTN Enterprise Media Gateway Enterprise Media Gateway IP Telephone IP Telephone Carrier Media Gateway CLASS Switch CLASS Switch Carrier Media Gateway TDM IP TDM IP IP Islands of Enterprise IP… • With older TDM connectivity we have islands of IP • This is not a good model for sharing unified communication services among enterprises • However, with all-IP connectivity…

  13. IP Bridging the Islands… TDM Telephone Carrier Softswitch Enterprise Softswitch Enterprise Softswitch PSTN Carrier IP Infrastructure Enterprise WAN Router Enterprise WAN Router IP Telephone IP Telephone • …we can envision B2B enhances services • High Definition Voice • High Definition Video • Federated / Shared Presence State Information • Secured B2B Text Messaging

  14. You converged your internal network, SIP Trunking converges your external network.
