Strange issue that I can’t figure out and I am hoping someone may have some ideas. Two Asterisk boxes running 1.2.34 (yeah I know it is old, but it runs like a top and I am not going to mess with it). *B rsyncs config from *A. *A dies. I bring up *B and it all works fine, except for one issue. Calls to voicemail are garbled and low. Phone to phone and phone to gateway work perfect. If I get voicemail emailed to me, it sounds perfect. If I call into voicemail, the prompts and the message are garbled. There is no packet loss or any issues like that as all other calls sounds fine. The only issue is calls to voicemail from what I can tell. We have thousands of calls a day, so I am quite sure I would have heard if there were other issues. Any ideas? My first guess would be timing, but it isn’t stuttery or anything, it is just kind of fuzzy and quiet and I can’t imagine timing would affect that.
