6 SIP Trunking is Hot SIP Trunking is currently the fastestgrowing segment of VoIP services. It s expected to have an 89 percent CAGR from 2008 to Infonetics Research 6

7 SIP Trunking is only the Beginning To date, SIP trunking has been largely focused on recreating current TDM voice services ( trunks ) over IP. While useful, that s only one possible use. We see the true market potential of SIP trunking in its ability to act as a hosted services conduit and to carry media other than standard PSTN quality voice capabilities impossible with TDM. - Broadsoft 7

8 NAT/Firewall Traversal Problem when SIP Trunking over the Internet Public Internet SIP Trunking Provider SIP System GW PSTN SIP Trunking does not pass a SIP unaware NAT/firewall! IP-PBX Firewall and the firewall cannot be opened enough to make it work because of NAT. 8

9 With a SIP Trunk over the Internet, it is not really an option to just connect it to a VoIP LAN. Public Internet SIP Trunking Provider SIP System GW PSTN IP-PBX Firewall SIP Trunk Over the Internet Severe Security Warning! No one wants the whole Voice LAN exposed to the Internet. Any extra firewall here needs to be SIP aware or widely open. Who will issue a public white IP Sept. addresses 2009 to every Phone? Data LAN VoIP LAN No Soft or Multimedia Clients!?? UC? 9
