When a call is set from PSTN and nobody answer on phone connected to FXS port if the calling party off hooks the phone the phone connected on FXS port remains more than 40 seconds ringing.
I have checked several post about this but no success up to now.
for the moment I tried the following option
timeouts call-disconnect 0
timeouts wait-release 1
description FAX 1190
any config that have been confirmed it works fine?
