First of all, what is SIP trunking?

SIP stands for Session Initiation Protocol, which is a protocol used in VoIP communications allowing users to make (mostly free) voice and video calls. This protocol establishes sessions and manages signaling, in addition to terminating the connection at the end of sessions.

As for SIP trunking, the term “trunk” is something of a misnomer in VoIP technology; it is derived from older technology where a “trunk” was a physical bundle of wires connecting the organization to the phone carrier.

A SIP trunk does not consist of physical wires, instead taking the form of an Internet connection to the Internet telephony service provider (ITSP). Nonetheless, the term “SIP trunking” has gained broad acceptance in the VoIP community.

Why might you require a SIP trunk? 

    • Save on costs. Financial benefits have long been among the most frequently cited reasons among organizations deciding to invest in SIP trunking; past research has even suggested SIP can deliver savings of 50% for businesses compared to private rate interface (PRI) telephony. Your own company may be very attracted to the prospect of immediately and significantly lowering the recurring costs of voice communications. 
    • Boost flexibility and scalability. You might also invest in a SIP trunk for the ability that it gives your organization to quickly scale up or down in accordance with its current needs. 
    • Enhance security. If you fear that IP phone lines may pose an information security risk to your business, it’s well worth considering SIP trunking as a more secure alternative to analog phone lines.
