registration, the current registration will time out. Check your SIP server for a
reasonable value.
F) Outbound Proxy
Outbound proxy is a device that receives requests from a client, even though it may not
be the server resolved by the Request-URI. Outbound proxy will forward SIP requests and
frequently RTP media traffic to another SIP server. Outbound proxy is used for a number
of reasons, including, firewall traversal – both in parallel with a firewall and situated in
the Internet as a Session Border Controller; and also for hiding customer IP addresses –
calls are all routed through one point so that a public ITSP IP address can be used for
accessing customers, rather than the customer’s own IP address.
Check with your SIP server (SIP provider) if an outbound proxy is required.

SIP Networks sometimes use the Home Domain name as an identifier. Enter this field if it
is required.

Forward is set.

the Backup Server.
