I was running SER 0.9.0 with mediaproxy and the default mediaproxy ser.cfg. I tested two xten clients behind two 2wire 180hg firewalls. Everything works perfectly if both clients use port 5060 for signaling. However, if you change either or both to a different signaling port, such as having each client listen on port 11111, then SER inserts incorrect entries into the via and record route sets. It will list itself as sip:ser.whatever.com:11111 when you call a t_relay. The call can set up fine, but you end up losing the bye's and cancels. Has anyone else noticed this problem? Thank you, SG
