SIP Telephony

What is SIP Telephony?

SIP (Session Initiation Protocol) is the standard used to set up and manage voice calls over IP networks. A SIP trunk replaces traditional phone lines with a connection to a telecoms provider over the internet or a dedicated link, carrying calls to and from the business phone system.

Why it matters

Moving to SIP makes it easier to add lines and extensions, keep numbers when moving office, and connect several locations into one phone system.
