FXS remains ringing many seconds

Unanswered Question
Aug 9th, 2010


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

voice-port 0/3/1
cptone MX
timeouts call-disconnect 0
timeouts wait-release 1
description FAX 1190

any config that have been confirmed it works fine?


I have this problem too.

Check with "debug vpm signal" that when the calling party hangs up, the router is made aware and can tear down the call to FXS.
