We just upgraded to FreePBX 15 from 13 a little over a week ago. Generally, things have been working well and I’m trying to iron out some small issues.
The biggest issue we’re having once in a while is when an outside call comes in, the receptionist puts them on hold. The outsider is on hold and hears the music. But when the receptionist comes back and tries to pick up the parked call, the receptionist hears the on-old music. Eventually the outside caller will hang up and call back in.
