FXS remains ringing many seconds

filiberto.aguirre · ‎08-09-2010

Hi,

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
disconnect-ack
cptone MX
timeouts call-disconnect 0
timeouts wait-release 1
description FAX 1190

any config that have been confirmed it works fine?

regards

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.
