What are SIP Trunks?

What are SIP Trunks?
SIP trunking is Voice over Internet Protocol (VoIP) & streaming media service based on Session Initiation Protocol (SIP) by which Internet telephony service providers (ITSPs) deliver telephone services to business equipped with SIP-based private branch exchange (IP-PBX). Put simply, your calls go over the internet instead of traditional telephone wires.

Exactly what is SIP Trunking?

A SIP Trunk is a virtual phone line that connects your phone system to the public telephone network. It sends the data over a data network, instead of over an ISDN circuit. SIP Trunks can be used instead of ISDN circuits to carry all of your telephone calls, or in conjunction with an ISDN circuit to provide a resilient telephony solution

How many trunks will i need?

That depends on how many simultaneous calls you expect to take place at one time. Obviously, this will depend on your business. If you’re running a call centre it could be one SIP Trunk per operator. For more typical companies, you’d usually have one SIP Trunk for every 5 or 6 phones.

Is SIP reliable?

Yes when set up correctly. The data connectivity over which the SIP Trunk runs needs good reliability.
