--------------------------------------------------------------------

I've got a patch for this issue that I want to try out, but I've been having a lot of trouble reproducing the issue. I usually end up in a situation where an audiohook will simply not execute on frames when the codec has no translation path to ulaw, but here the audiohook attempts to translate even after this check is (or would normally be) made.

I'd like to get some more information if you could... the following to be specific:

1. all log messages from the start of the call to the end of the call that triggers this crash

2. All extensions involved with the call. If the call is to stasis, all Stasis commands ran in order.

3. Configuration for the endpoints involved with the call. I think you are using chan_sip, so the endpoints used in sip.conf... not including sensitive information like passwords and IP addresses. Codec order would be a good one to have in particular. If the endpoints are defined via realtime, the CLI output for 'sip show peer <peername> load' works fine too.
