SIP Proxy Handling

Overview:

This feature allows the IMG to interact with SIP Proxy Servers and Session Border Controllers as intermediate routes between domains. The IMG can route SIP traffic to these SIP entities (SIP proxies) and with the knowledge of their final destination (remote SIP UA).

A SIP Proxy receives SIP requests from a client, even though it may not be the server resolved by the Request-URI. Typically, a UA is manually configured with an outbound proxy, or can learn about one through auto-configuration protocols.

You can configure one SIP Outbound Proxy Server for each external SIP gateway using the SIP Proxy pane under a SIP Profile and then assign that profile to the External Gateway.
