Cisco IOS XE versions. It can be noted that by default the outgoing SIP Request-URI and To header URI have the session target of the outbound-dial-peer. This can be disabled by using the command requri- passing which allows the gateway to pass the in-leg URI host portion to the out-leg instead of replacing the URI host portion with the session-target. The command requri-passing was added in 15.4(1)T and Cisco IOS XE 3.11S. Configuration Example

voice service voip sip call-route url requri-passing ! voice class uri CUCM sip host dns:.*.com ! dial-peer voice 777 voip description OUTGOING URI session protocol sipv2 destination uri CUCM session target sip-uri !
