Joshua Elson commented on ASTERISK-30148:
-----------------------------------------

So in this setup, we are not using Asterisk realtime, but the path does look similar. We are able to reproduce this with some frequency. Any new thoughts on additional debugging or info we can provide to help? Or any other workarounds here?
