SIP trunking is the IP connection between an IP-PBX and a service provider
SIP Trunking is Hot
• SIP Trunking is currently the fastest-growing segment of VoIP services. It’s expected to have an 89 percent CAGR from 2008 to 2013. – Infonetics Research

The SIP Trunking Challenge
• "Interoperability is a challenge facing SIP trunking. There are organizations such as the SIP Forum looking to solve such problems, but at the end of the day, realized end-to-end solutions for customers with multiple vendor and service provider solutions will continue to be an obstacle," (Rebecca Swensen, Research Analyst, IDC)

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

SIP Trunking does not pass a SIP unaware NAT/firewall!
…and the firewall cannot be opened enough to make it work because of NAT.

With a SIP Trunk over the Internet, it is not really an option to just connect it to a VoIP LAN.

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.
