I have a dial peer configured in this way:
dial-peer voice 5 voip application session destination-pattern 2[0,1,5]. session protocol sipv2 session target sip-server
and when I debug on the router the dial-peer is correcly matched. However the gateway doesn't send the INVITE to the sip server but directy to the "nat_public_ipaddress
What's the refer-to look like? If there is a match, then cisco uses the refer-to field uri. It doesn't replace the domain in seesion target.
