SIP Trunking and How it Works?

SIP is the protocol that sends high-quality voice and unified communications via the internet from one end to another. This means that you can make and receive business calls virtually (over the cloud).

A SIP trunk can hold multiple SIP channels, and each channel works as an inbound or outbound call. And so, your business can make multiple calls simultaneously using one SIP trunk.

All you need to do is have a global SIP service from a SIP trunk provider and integrate it into your existing PBX system.
