What is a Voice Gateway?

A voice gateway is a device used for call termination when you require communication between your IP telephony infrastructure and a PSTN (public switched telephone network) or other non-IP devices, such as PBXs (private branch exchanges), analog phones, fax machines and modems.

A trunk interface lets you specify how the voice gateway will communicate with the non-IP devices. It does this through time-division-multiplexing (TDM) signaling.

The Cisco Unified Communication Manager (CUCM) supports the following voice gateways:

  • Standalone Voice Gateways

  • MGCP Gateways

  • H.323 Gateways

  • SIP Gateways

CUCM also supports a number of TDM interfaces, such as digital T1/E1, Foreign Exchange Office (FXO) and Foreign Exchange Station (FXS), which are dependent on the Cisco gateway that you are using.
