Chapter 5 Parameters and Defaults

SIP Parameters

If the outgoing SIP request has a ROUTE header, the first route in the header is removed if it resolves to the same IP address as the out-bound-proxy. This process guards against the case when the out-bound-proxy also inserts its IP address into the RECORD-ROUTE header.

The OutBoundProxy parameter can be an IP address with or without a port parameter, such as 123.123.110.45, 123.123.110.45.5060, or 123.123.110.45:5061, or a URL such as sip.cisco.com, sip.ata.cisco.com:5061. For IP addresses, a period (.) or colon (:) can be used to delimit a port parameter. For a URL, a colon (:) must be used to indicate a port. If no port parameter is specified, the port 5060 is assumed.
