I have a clean new build of Asterisk 184.108.40.206 from source. I use 2 TDM400P cards. One contains fxs and the other fxo cards.
I am in the UK and have 4 BT pots lines. 1 of them is a normal stand alone line (???888) and works perfectly on any of the fxs ports. The other 3 all share a common number (???444) and receive incoming calls without a problem.
My problem is that recently, I have started having difficulty making outbound calls over the 444 lines. The line picks up and Asterisk dials, the called party answers and asterisk immediatelly shows the call as hung up, although the called party has not done so. At first this was happening on just one of the 3 combined lines, but now it is happening on all of the lines all of the time.
If I swap the 888 line into one of the ports used for a 444 line, it works perfectly.
I’m at a loss to know where to start debugging this, even with a very verbose console setting, asterisk doesnt report anything other than that the called party hung up.
The reason this is a clean new build is that I tried the same setup with both trixbox and *now packages. The behavior has been virtually identical.
Any suggestions of where to go now greatly appreciated.
Happy to post whatever logs and configs may be required, but haven’t so far as this is wordy enough already.
