Functional Notes
Enabling force-port-translation allows the SIP Proxy to create a unique registration in the user database
for the same user from multiple phones. This feature retains the key generated by the proxy and inserted
into the user portion of the Contact header. It also uses the source port that is generated by the firewall
when doing NAT. The source port is inserted at the end of the host portion of any address translated in the
SIP header. Enabling the exclude-via parameter on this command, excludes the Via header from the
source port translation.
Usage Examples
The following example enables force-port-translation:
(config)#ip sip proxy force-port-translation
60000CRG0-35E
Indicates excluding the Via header from port translation.
Command was introduced for AOS data products.
