Appendix D SIP IP Phone Parameters
outbound_proxy_port
(Optional) Port number of the outbound proxy server. Default
is 5060.
When an outbound proxy is enabled, all SIP requests are sent to the
outbound proxy server instead of to the proxy
x
_address. All
responses continue to reconcile the normal Via processing rules.
The media stream is not routed through the outbound proxy.
NAT and outbound proxy modes can be independently enabled or
disabled. The received= tag is added to the Via header of all
responses if there is no received= tag in the uppermost Via header
and if the source IP address is different from the IP address in the
uppermost Via header. Keep the following rules in mind:
•
If a received= tag is in the uppermost Via header, the response
is sent back to the IP address contained in the received= tag.
•
If there is no received= tag and the IP address in the uppermost
Via header is different from the source IP address, the response
is sent back to the source IP address.
