What is SIP Trunking?

SIP Trunking is an Internet-based technology that provides a connection between Voice Over IP (VoIP) clients and the Public Switched Telephone Network (PSTN) and has all but replaced the traditional landline circut as the standard for the delivery of local and long-distance services to businesses. For over 15 years now, IPComms has delivered over 50,000 SIP trunks to thousands of businesses, call centers and resellers looking to get the most out of their existing PBX investment.
