hello, I was wondering how can modify the sip from and contact headers? I need to pass the phone number in the username not "1-F2la9<sip:1-F2la9@4.55.35.60:5070;transport=udp>" to level 3. also i need to do the same with the contact header the username needs to the phone number not "gw+level3<sip:gw+level3@10.126.200.6:5060;transport=udp;gw=level3>". also why is fs switch send our internal ip address and not our external ip address in the contact field, do i not have something setup correctly?
