  5. 5. 5© COPYRIGHT 2017 DIALOGIC CORPORATION. ALL RIGHTS RESERVED. Overview: Transition to IP Networks  Transition to IP networks is well underway › Service providers and enterprises migrating customers to IP networks › SIP trunking provides an IP connection between enterprises and carrier › A recent study from IHS technology notes that 47% of North-American respondents use SIP trunking today*  But T1/E1 trunks using TDM (Time Division Multiplexing) have not gone away › Models for building service provider networks also evolving  Next Generation Networks (NGN) using a mix of TDM and IP technologies migrating to an all-core, but still widely deployed  All IP core is built using the sip-centric IP Multimedia Subsystem (IMS) and Long Term Evolution (LTE or 4G) radio technology  Fixed line networks also adapting an IMS model * IHS Technology – SIP Trunking and eSBC Strategies – North American Enterprise Survey
  6. 6. 6© COPYRIGHT 2017 DIALOGIC CORPORATION. ALL RIGHTS RESERVED. Why Circuit-Switched Networks Still Matter  During the transition to IP, enterprises and carriers still need to connect to existing networks  Signaling system #7 (SS7) widely deployed for all 2G / 3G mobile networks and many fixed line networks  ISDN trunks still widely used by enterprises who haven’t switched to SIP trunks or communicate over networks where SIP trunking not yet available  Hybrid technologies such as SIGTRAN provide ways of running stacks such as SS7 over IP transport  Many popular telecom services such as conferencing, unified messaging, contact centers and hosted IP Centrex run as SIP applications, but need to support circuit-based customers  For all of these reasons, interconnect technologies such as media gateways, signaling gateways and softswitches still play a valuable role in “connecting the dots” between IP and TDM  During 2016, just under 75 million media gateway channels were sold in the global market per IHS technology* * IHS Technology Service Provider VoIP and IMS Equipment and Subscribers Market Tracker – May 2017
  7. 7. 7© COPYRIGHT 2017 DIALOGIC CORPORATION. ALL RIGHTS RESERVED. Strategies for Interconnecting TDM and IP Networks  Media gateways are a key approach for interconnecting TDM and IP networks › Key functions are:  Signaling translation to control the calls or sessions  Media translation (transcoding) for voice, fax, tones and sometimes video  Media gateways can be integrated or de-composed › Integrated media gateways incorporate signaling translation within the gateway › De-composed or NGN gateways rely on a separate softswitch for signaling › Both integrated and de-composed media gateways provide media translation between TDM and IP  Most common signaling translations are: › ISDN PRI (TDM) to SIP (IP) › SS7 (TDM) to SIP › Others signaling sometimes used includes CAS (TDM), H.323 (IP), SIGTRAN (IP)  Common media translations are: › Voice – convert G.711 (TDM) or GSM mobile TDM) to IP codecs (G.729, G.723.1, iLBC, AMR-NB, AMR-WB) › Fax – convert T.30 (TDM) to T.38 packets or G.711 over IP › Voice – convert in-band tones to IP representations (most common are RFC 2833 and SIP INFO)
  8. 8. 8© COPYRIGHT 2017 DIALOGIC CORPORATION. ALL RIGHTS RESERVED. Strategies for Interconnecting TDM and IP Networks Any to Any Signaling Example  An example of “any to any” signaling translation as provided by the Dialogic® IMG 2020 Integrated Media Gateway is shown in the table below: ISDN PRI SS7 ISUP SIP H.323 SIP-T/SIP-I ISUP/M3UA AS TDM ISDN ✓ ✓ ✓ ✓ ✓ SS7 ISUP ✓ ✓ ✓ ✓ ✓ IP SIP ✓ ✓ ✓ ✓ ✓ ✓ H.323 ✓ ✓ ✓ ✓ ✓ SIP-T/SIP-I ✓ ✓ ✓ ISUP/M3UA AS ✓ ✓ ✓ ✓ ✓
  9. 9. 9© COPYRIGHT 2017 DIALOGIC CORPORATION. ALL RIGHTS RESERVED. Bridging the Gap: SIP Trunking via Media Gateways with SBC functions  SIP trunks connect enterprises to service providers › Gradually replacing ISDN PRI trunks, but media gateways can support both  SIP forum has developed SIP connect agreements › Designed to interconnect enterprise PBXs and service provider networks › Use specific subset of SIP operations for SIP trunking › SIP connect 2.0 is latest version; compliance tests available for 1.1  Some media gateways can connect either IP or TDM PBXs to SIP trunks › SBC functions such as firewall, topology hiding, bulk registration can be used by SBCs or media gateways in SIP trunking applications Service providers Enterprise Dialogic® IMG 2020 VoIP PSTN SIP trunk PRI SIP TDM IP / TDM / PBX
  10. 10. 10© COPYRIGHT 2017 DIALOGIC CORPORATION. ALL RIGHTS RESERVED. How Media Transcoding Adds Value for Gateway Customers  Traditional media gateway converts TDM media to IP packets  Digital Signal Processor (DSP) hardware in gateways can also transcode between different IP encodings  As needs for TDM – IP media conversions declines, can re-purpose gateways for transcoding › Provides investment protection for customers  Some gateways can support simultaneous TDM – IP and transcoding operations  More flexible gateways also able to support all-IP signaling translation (SIP – SIP) and transcoding Mobile operator Dialogic® IMG 2020 Carrier-to-carrier Mobile operator – VoLTE/4G SIP / AMR-NB SIP / AMR-WB MSC/MGW IMS core
