Enterprise SIP Trunk

Overview

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.

How It Works

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.

Breaking the Limitations on T1

IDA-P Enterprise SIP Trunk
TDM-based, mainly for voice communication IP-based, supports not just voice but also video communication
Scales up by trunk only, increments at 24 channels per step Highly dynamic channels, clients subscribe to what they need
Limited to 24-channels per trunk and the need to install T1 cards circuits No limitations to the number of channels in the trunk, much faster to expand
Requires additional IDA interface card Lower CAPEX, no additional interface card required for channel expansion
