Voice Mail or IVR hangup holds zap channel open
Submitted by dhallman on Sat, 02/16/2008 - 4:45pm.
Hi James,
Thank you for the suggestions getting the last bugs out of my recent Install.
After upgrading the system with yum, upgrading to FreePBX 2.4, installing the latest Rhino updates/firmware DID+Zap channel routing has the incoming calls routing correctly.
I am however seeing a new issue.
Any caller that hangs up on any recorded message (voicemail or IVR) holds the zap channel open forever! I unlocked one channel using FOP had listed as live for 5 hours!
My provider is Bell Canada. Has anyone else identified this? Is there a workaround?
Thanks!
Dwayne

This morning channel 3 was locked open recording a message for over 70 min. The caller had long since hung up. I can cause channel 4 to lock open anytime by calling, waiting for the IVR and hanging up during the message. Sometimes it plays the message 3 times and exits, other times it plays 3 times and locks.
Has anyone confirmed any of this? Is there any work around?

Barge it

Barge the channel and see what you hear. Is it a busy signal or silence? You can use busydetect to close the line if you hear a busy signal. Be very careful with it as it can also sometime cause false hangups. Here is a well documented zapata.conf that has the busydetect settings in it for reference.

A better fix is to find out if your telco supports answer/disconnect supervision. I often have to call 3 or 4 times before I get a rep that knows what that is. If their switch supports that feature, your problems will disappear.
