SIP Trunking: Growing, But T1 Remains the Mainstay

Although many organizations have deployed VoIP on their premises, they still use legacy technologies to connect to the PSTN, with T1 lines the most commonly used trunking service today through 2012, according to Infonetics Research.

Much of the SIP trunk demand is fueled by fast-growing hosted IP telephony services. For the first three months of 2009, service providers experienced an average of 40 percent to 50 percent year-over-year growth for IP Centrex, indicating the demand for outsourcing and managed solutions.

Infonetics Research expects hosted UC services to take off, with worldwide revenue doubling between 2009 and 2013, and we forecast SIP trunking service revenue to hit an 89 percent compound annual growth rate from 2008 to 2013.

It also is worth noting that many carriers interconnect with each other using T1 protocols, even if end user service is supplied exclusively in the IP domain.

SIP trunk use is growing, and by 2012 will be the second most commonly deployed trunking service, says Infonetics.

AT&T and Verizon are used most often as providers of SIP trunking services, survey respondents said.
