SIP Trunking for your Business: UC Tech Chat [Video]

By Brian Ferguson

DigiumSIPSIP, or Session Initiation Protocol, is the standard communications protocol for voice and video in a Unified Communications (UC) solution across a data network. A SIP trunk replaces the need for traditional analog, T1-based Public Switched Telephone Network (PSTN) connections with termination instead provided over a company’s public or private Internet connection through a SIP provider. These SIP providers, often referred to as Internet Telephony Service Providers (ITSP), provide PSTN service on a per minute or channelized pricing model.

The SIP trunking adoption rate will inevitably grow in the coming years, according to an Infonetics Research report, which stated that 58 percent of American businesses said they plan to use SIP trunks in 2015, up from 38 percent in 2014.

In this week’s episode of UC Tech Chat, we discuss how SIP trunking works, and how it can benefit your business. Later in the show, VoIP expert Julie Webb answers a question from her inbox. The treat at the end of the show is a flashback of our favorite phone songs from the 80s.

    I am also using IAX Trunking and have found it to work very well. The motivation was a little better security through the firewall.

    I would like to see more providers offer IAX.
