[OpenSIPS-Users] Record-Route port is not the same as local used port

Hi Royee,

OpenSIPS will add the in the 2 RR headers the inbound and outbound 
listening interfaces (if not override by an advertise address). So can 
you share the listening sockets you have (priv versus public), the 
advertise value and what you get into RR headers ?
