We have been using asterisk for a while now but have recently needed to install a second server in a remote office and set up a iax trunk between the 2 servers. The dial plan seems to work well when I tested it on the same LAN. However this afternoon I connected the system at the remote office and made some calls. All the calls connect and work fine, voice quality is great no really couldn’t have hoped for better. Hang up the call and tried to make another call and nothing, the link was not responding, after much trouble shooting I have found that after the call is hung up the 2 asterisk servers seem to go into some kind of loop sending each other message. I have pasted a debug for both servers below that include everything from the start of the call to after hangup. I have cut them short at the VNAK and Hangup cycle just continues for 30seconds or so flooding the link completely.
Any help you may be able to provide would be greatly appreciated
