I have a TDM400 Pots card in my asterisk box.
2 FXO modules and 1 FXS module.
System has been running fine for months, then all of a sudden today, the phone connected to the FXS module has stopped ringing. When picking it up I get no dial tone.
Rebooted the server tried again got a dial tonenow, hung up no dial tone again. Tried to call the FXS extension, phone did not ring, but asterisk said it was calling it and it was ringing, but Picked up anyway and was able to talk without a problem, even though the phone was not ringing.
Hung up then tried again no dial tone. Hung up and tried again this time got a dial tone, tried to dial numbers no repsonse asterisk didnt even log i had opened the channel.
Basically the FXS has stopped working, i’ve changed nothing in the config for months, i’ve tried 3 different phones all give the same problem.
There are no errors logged in any of the log files for asterisk, so I assume it is a hardware error.
I’m a bit at a loss here.
I’m assuming the tempermental operation of the fxs module implies it has blown up and i need to get another one?
Does anyone have any ideas?
