What is SIP Trunking?

SIP (Session Initiation Protocol) Trunking is a method of sending voice and other unified communications services over the internet.

Instead of using traditional phone lines (PRI or analog), SIP trunks connect your business phone system (PBX) to the internet via an ITSP (Internet Telephony Service Provider).

SIP Trunking is the backbone of modern VoIP (Voice over IP) solutions, enabling cost-effective, scalable, and flexible communication options for businesses across the United States.

Eliminate costly PRI lines and reduce long-distance/international charges.

Add or remove lines (channels) as your business grows – no physical rewiring needed.
✅ Disaster Recovery:
Reroute calls instantly in case of outages or emergencies.
✅ High Voice Quality:
HD voice codecs ensure clear, reliable communication.
