asterisk users - Sep 2008 - Speech recognition on simultaneous SIP / PSTN calls

Hi. I'm writing a speech recognition module for Asterisk. I'm having
problems with simultaneous SIP and PSTN calls. Sometimes Asterisk crashes in
this scenario. I don't have problem with simultaneous calls using PSTN calls
only.
The implementation is in the file res/res_speech.c
Does someone know if the isolation differs in these two protocols? Each
function has its own mutex, but the crash still happening.
I'm using Asterisk 1.4.21.2

Thank you.
