VoIP Domains

There are five types of VoIP Domain objects:

• VoIP Domain SIP Proxy

• VoIP Domain H.323 Gatekeeper

• VoIP Domain H.323 Gateway

• VoIP Domain MGCP Call Agent

• VoIP Domain SCCP Call Manager

In many VoIP networks, the control signals follow a different route through the network than the media. This is the case when the call is managed by a signal routing device. Signal routing is done in SIP by the Redirect Server, Registrar, and/or Proxy. In SIP, signal routing is done by the Gatekeeper and/or Gateway.

Enforcing signal routing locations is an important aspect of VoIP security. It is possible to specify the endpoints that the signal routing device is allowed to manage. This set of locations is called a VoIP Domain. For more information, see the R81 VoIP Administration Guide.
