What is SIP Trunking?
SIP Trunking is a technology that allows businesses to communicate via voice and video over the internet instead of traditional phone lines. SIP (Session Initiation Protocol) is a protocol used to manage IP-based communications, while trunking refers to routing multiple connections through a single line.
By integrating with PBX (Private Branch Exchange) systems, SIP Trunking enables businesses to use VoIP (Voice over IP) services, reducing costs while enhancing communication quality and flexibility.
How Does SIP Trunking Work?
SIP Trunking replaces traditional phone lines by transmitting voice, video, and messaging data in packets over the internet. The core process works as follows:
-
PBX Integration: SIP Trunking connects to an enterprise PBX system, linking it to the outside world via the internet.
-
VoIP Service Provider: The service is provided by a VoIP provider that routes calls over the internet.
-
IP-Based Communication: Incoming and outgoing calls are routed through IP networks, eliminating the need for traditional phone lines.
-
Scalability and Flexibility: Businesses can easily add or remove lines as needed.

✅ Lower Costs: More cost-effective than traditional phone lines.
