What is SIP Trunking in Internet Telephony?

SIP trunking is an advanced service that plays a key role in connecting PBX (Private Branch Exchange) systems to the modern digital communications network. This service uses Internet Protocol technology - specifically the Session Initiation Protocol (SIP) - to replace traditional telephone lines and thus create a direct connection between your telephone system and the public telephone network via the Internet.

SIP trunking replaces the traditional way of making calls with a more efficient and cost-effective method. Companies benefit from a scalable and flexible communication solution that allows them to use their existing PBX infrastructure to transmit voice, video, and data services over the Internet.

This innovative connection method brings numerous benefits, including improved resilience, lower operating expenses and greater adaptability to a company's ever-changing communication needs.
