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.
