What is a SIP Trunk?

SIP Trunk is a virtual phone that uses a data circuit

A SIP Trunk is a service that provides the same effect that you get from a traditional phone line, with the difference being a SIP Trunk is a virtual phone that uses a data circuit. It is a direct connection between your business and an Internet telephony service provider (ITSP). It enables you to extend voice over IP (VoIP) telephony beyond your business’ firewall without the need for an IP-PSTN gateway. In addition to calls using VoIP, SIP trunks can also carry instant messages, multimedia conferences, user presence information, Enhanced 9-1-1 emergency calls, and other real-time communications services. SIP Trunking is a configuration that is overall less expensive to operate, maintain, and upgrade..
