What does 1 x SIP Trunk equate to?

A SIP trunk is essentially a virtual connection that allows for voice over IP (VoIP) calls, enabling multiple voice channels over a single data connection. The accurate representation of what one SIP trunk equates to is one voice line. This alignment stems from the fact that a single SIP trunk can carry multiple concurrent calls, but in terms of the general equivalence for basic understanding, it is often equated to one voice line, where each voice line corresponds to one telephone number or call path.

In this context, thinking of a SIP trunk as a voice line provides clarity on its function in telecommunications. While DSL lines, T1 lines, and Ethernet lines serve various internet and data transmission purposes, they do not directly relate to the specific function of handling VoIP calls that SIP trunks provide. This is why the association with one voice line is the most accurate representation of a SIP trunk's capacity in general use cases.
