Hi Max,

You need to inspect the SIP messages and check if your SDP is carrying
the proper IP/port for each side of your ALG.  Make sure that your
openser is providing proper IP in SDP for each network:
 - private IP in SDP for SIP messages originated by the interface
sitting on the private network side
 - public IP in SDP for SIP messages originated by the interface
sitting on the public network side


Regards,
Ovidiu Sas
