UM IP Gateways

UM IP gateways are created in Active Directory to represent a Voice over Internet Protocol (VoIP) gateway device. UM IP gateways are created in an enabled state. A UM IP gateway establishes a logical link between the IP gateway, the UM dial plan, and a single or multiple UM hunt groups.

Note:
An IP gateway performs the conversion between circuit-switched protocols and packet-switched protocols, such as Session Initiation Protocol (SIP) and Realtime Transport Protocol (RTP).

Before the IP gateway can process calls, it must be represented by a UM IP gateway. You must then associate the UM IP gateway with a UM dial plan. You can associate a UM IP gateway with one or more UM dial plans by creating one or more UM hunt groups.
