This was working until I recently updated all modules that had updates pending on FreePBX.
When someone calls a Google voice number, Asterisk ‘sees’ the call and the logs show that the call is answered but the person calling continues to hear ringing on the other end. Then the call terminates with an exited non-zero but the caller still hears ringing until the Google voicemail picks up.
I uninstalled motif and re-installed, still the same.
