What is SIP Trunking?
6
SIP Trunking is Hot

• SIP Trunking is currently the fastest-growing
  segment of VoIP services. Its expected to have
  an 89 percent CAGR from 2008 to 2013.
• Infonetics Research

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, thats 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

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

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)
