Asterisk faxes jamming

We’ve been using Asterisk here in the office for several months now. It handles our voip phones and also incoming faxes.

We have always had a problem with the fax line ‘jamming’. Every now and then the fax would get stuck while receiving a fax. To rectify this we would have to restart asterisk.

This morning one of our clients couldn’t get a fax to us. It kept jamming at our end. They must have tried about four or fives times. Same problem each time.

So I decided to try and fix this problem.

To cut a long and boring post short, I found this posting to the Asterisk Users mailing list which has a fix. It involves increasing the gain on the card that has the fax line.

I gave it a go and on the next attempt the client’s fax came through perfectly. Coincidence?

Perhaps, but this tip from Paul is definitely worth a look.
