             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Codecs/codec_siren7
    Affects Versions: 11.13.0
         Environment: Debian 3.2.63-2 i686 GNU/Linux
Asterisk 11.13.0~dfsg-1~bpo70+1
Digium Siren7 Module Version 11.0_1.0.5 (optimized for i686_32)
            Reporter: Daniel Ammann


Using Siren7 codec throws a segfault at random times during a call. THe Endpoints involved are different Polycom IP6000 and IP7000 phones

At the time of the crash, several Polycom endpoints were using this asterisk instance with siren7 codec in parallel. The typical usage scenario is that those endpoints are participating on app_conference based conferencing, and transcoding is happening for those endpoints (siren7 -> slin16)

This problems occurs in guesstimated 1 out of 20 calls, and minutes to hours after the call has been established

I can make core dumps available if helpful
