The device is a great gateway in order to built to support both TDM-to-SIP and SIP-to-TDM applications. In a TDM-to-SIP deployment, the gateway significantly reduces operating costs by connecting a legacy business phone system with dynamic SIP trunking services. SIP-to-TDM deployments use the gateway to connect a modern SIP communications system with T1/E1/PRI service from legacy carriers.

Other available facets are like:

• The G200 doubles the capacity with two T1/E1/PRI interfaces and up to 60 concurrent calls. Both models have integrated echo cancellation, a small footprint (1U, half-width, and half-depth) and no failure-prone moving parts.
• In a TDM-to-SIP deployment the VoIP gateway significantly reduces operating costs by connecting a legacy business phone system with dynamic SIP trunking services.
• SIP-to-TDM deployments use the VoIP gateway to connect a modern SIP communications system with T1/E1/PRI service from legacy carriers.
