Hi
I was using play_and_detect_speech with Nuance Speech Server 5 and it generally works great! Much thanks to Chris Rienzo for this cool App :)
There are 2 cases where I need help to understand what is happening.
1. In general my SIP connection between mod_unimrcp and Nuance works fine with all the calls answered. But in 3 repeated cases, the SIP connection was not established as a result of which the call got hungup.
Is there any graceful way in play_and_detect_speech (like some channel variable set) which can be used to find if the SIP call has been answered by Nuance or not.
Like in this case, I got

2. After performing a recognition with a low confidence score, the call got disconnected but FreeSWITCH could not detect the call disconnection and repeatedly gave the following debug message in the log till it flooded hundreds of log files.
switch_core_session.c:2102 FreeTDM/1:2/4948608 Channel is hungup and application play_and_detect_speech does not have the zombie_exec flag.
During this "show calls" on fs_cli will crash fs_cli
I had to shutdown freeswitch.
