VXML Application not exiting on caller hangup during TTS Playback

josephdontz

We designed a custom VXML application that simply reads a .vxml file in the IIS directory that contains the verbiage the application needs to read back in the form of a /prompt, and then the associated grammars to press or say a DTMF tone.  What we are finding is that when the prompt playback is occurring and the caller hangs up, the session will hang until our application timeout value is hit.  We would expect some kind of disconnect hot event, but it isn't happening.  Below are the application logs.  Any tips to trigger a proper disconnect while TTS playback occurs?

This is most likely caused by a start of call class or action element at the top of the callflow not completing before the voice browser's fetch timeout occurred. To resolve it ensure this class executes in a timely manner or run it in the background. Session timeouts may also occur under high load or if there are issues with a load balancer or voice browser.

Hi Joseph 

 

my team ran into this issue as well; by any chance are you using VVB? and would you mind telling me which version?
