[asterisk-speech-rec] SpeechDeactivateGrammar call after the caller hangs up

[sysadmin at airlinksystems.com]

Hello,
I am using Asterisk 1.4, Lumenvox 8, on Fedora Core 7

I am having a problem where the SpeechDeactivateGrammar gets an error after the hangup and causes Asterisk to quit execution of the script.  If I don't hang up or do something that Lumenvox has to execute on, the SpeechDeactivateGrammar works ok.  Only on the hangup does the error appear.

This is a real problem because my script needs to do post processing after the call, even if the person hangs up during speech recognition.

Is there something I am supposed to do differently on the speech engine after a hangup, like not try to deactivate the grammar?


Thank You

Joe Johnson
