Chapter 14: HKBN Sip Trunk (PSTN) Configuration

What is HKBN Enterprise SIP Trunk?

Hong Kong Broadband Network’s Enterprise SIP Trunk service is fully designed to enhance and support a full range of business communications. Utilising the client’s network as its focal point, it significantly reduces telecom overheads while offering a rich array of features.

The Enterprise SIP Trunk is an IP access solution that enables direct service provider to enterprise connections of  IP PBX or SIP gateways over IP. Unlike a time-division multiplexing (TDM) trunk, a SIP Trunk is a direct SIP-to-SIP connection to the public switched telephone network (PSTN) without converting from TDM.
