Business Class SIP Trunks Overview

 

Technical Specifications for Business Class SIP Trunks

Time Warner Cable Business Class SIP Trunks offer an IP-based, voice-only trunk service using Session Initiation Protocol (SIP) to connect an IP PBX to the Public Switched Telephone Network. An Enterprise SIP Gateway (ESG) owned and managed by Time Warner Cable is then installed at a customer’s site. The ESG serves as a gateway and demarcation point between a customer’s IP PBX and the voice network. The ESG also enables Time Warner Cable Business Class to remotely monitor and manage the SIP Trunk service performance. SIP Trunks are provided via an Ethernet connection over fiber and hybrid fiber coax (HFC). If provided over HFC, Time Warner Cable Business Class will also install a cable modem to support the service.
