3 Traditional Networking Solutions are costly and inflexible H.Q Location Router PRI/ Voice Trunks Switches in most or every site Separate networks for voice and data no synergy PBX Branch Location Router PRI/ Voice Trunks PBX Small Office Location Router PRI/ Voice Trunks Key system Long Distance Network Costly gateways are needed to convert TDM voice to IP Trunks and phone numbers are tied to customer physical location High LD usage costs
4 The Enabler: SIP Trunking SIP Trunking provides a voice gateway to the through a data network or Internet connection Used in conjunction with an IP soft switch it provides flexible, scalable twoway access to the for call origination or termination Replaces high cost physical PRI / DS-3 circuits and voice gateways SIP Trunking allows interconnections to many different locations from a single connection Aggregates connections to different cities onto a single access SIP Trunking forms part of a foundation which can deliver new unified voice and data services to serve changing business needs. SIP environment allows for greater interaction of voice services with other applications, platforms, networks Enables access to public voice services beyond the
5 The Enabler: SIP Trunking From this Multiple networks for voice, data Many switches and local interconnects Fixed structure To this Same IP network used for data & voice SAVINGS! Consolidated PBX infrastructure & interconnects SIMPLICITY! Able to grow capacity and applications to suit needs FLEXIBLITY! IP VPN Network Soft switch Consolidated LD and Local
6 Leveraging SIP Trunking H.Q Location Router PRI/ Voice Trunks All on-net, off-net and LD voice uses single data network for transport eliminating voice interconnects Calls routed between different parts of the as local calls No need for local presence to acquire local phone numbers PBX Branch Location Router Network PRI/ Voice Trunks PBX Small Office Location Router PRI/ Voice Trunks Key system Long Distance SIP Trunking Costly gateways are needed to convert TDM voice to IP Trunks and phone numbers are tied to customer physical location High LD usage costs
7 Consolidated UC Solution Using SIP Trunking Primary Centre IP PBX CE Voice+ IP PBXs are consolidated in Centres Business offices can be operated with just phones and routers on-site Call control resides in secure data centres Overflow between locations to optimize voice bandwidth Business Office Locations PE CE Voice+ Allstream IP VPN Network PE SIP Trunking Secondary Centre IP PBX CE Voice+ Failover in the event communication is lost to one location Savings from centralized PBXs
