Hi,
When I make any outbound call from our IP-PBX to Adtran, Adtran is sending 400 bad request as response. There is no reason in the wireshark trace as to why Adtran is sending 400 bad request. The interesting part is at times I am able to make outbound calls at times but most of the time Adtran is sending 400 bad request. I tried disabling the firewall and checked to confirm that's not causing any issue. Can any one suggest what could be reason. Below is my configuration on Adtran.
