I have got some problem in my Tenor AXT 800 which I have been using for termiantion. The problem is that when my carrier calls, they get undefined error and I got the calls of duration of 32 second and nothing on the disconnect cause field. It has been happening for 2 hours before that it was working fine. I am attaching copy of CDR file of those calls of 32 second duration and disconnect cause field of null. Could you please check and correct my configuration. Here are the specifications.
