> I am developing a SIP App and whenever a certain combination of devices/users connect to the Asterisk server it crashes instantly with a Segfault. This only occurs when we are using speex and either dtx or pp_vad (with preprocess) is enabled.
> I've not been able to pointpoint exactly what the cause of this error is and what is needed to be reproduced.
> After some further investigation, it seems to happen when two users join the same ConfBridge conference.
