[Freeswitch-users] play_and_detect_speech errors

[Anita Hall]

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.
