The problem is when the channels reach our limit we lost sound quality.
The agents cant ear to the custumers becase that.

At least you have three channel types involved - chan_iax, chan_sip and chan_local... and it seems like you are using chan_agent as well...

Could you please confirm that this is still an issue with current (>r36460) branch 1.2 code?

Sorry, You want that I install a newer version and Test?

Well in few days I going to install a stage server for that.

Sorry for the delay and thanks.


Well in these moment I have a script that check the channels produce by AMD and checkes the elapsed time, If the time is more than 5 minutes Is hang up by the script.

Yes is crappy but at least the agents have a decent quality sound.

AMD isn't supposed to hang up the channel. All it does is return status and it's up to the person coding the dial plan to take what the next step is. I don't think this is a bug.

But How much time Does the amd application takes in order to check a call?

We have channels open by 30 minutes - 2 hours checking AM?

Is that normal? Because that screw my sound quality up once the channels rich our limit.

The show channels show these that is the same for every stucked channel:

furthermore, app_amd isn't a 1.2.X Asterisk application, so if you're running it, someone has backported it and you may have better luck getting support through them than here as we don't know what code is actually running here.
By: BJ Weschke (bweschke) 2006-07-07 09:32:26

this isn't a 1.2.X application.
