The title might not make total sense, but here’s the problem. When a ring group with confirm calls enabled points to an extension (including the # modifier) with follow me enabled, the cell phone in the follow me list is unable to answer the call. They get the message “call is no longer available or has been answered by someone else.” Unfortunately, if the follow me external device is the first one to pick up and press 1, it tricks the system into thinking the call has been answered, so everyone else will get the “call is no longer available” message, and the call will be lost.
I’m pretty sure this has been a problem ever since core version 18.104.22.168. I think I opened a bug report, but it got closed as a duplicate of the problem that was initially trying to be solved in that version. I’ve just been keeping the servers that need that functionality on the old version of core, but that is becoming difficult.
This is very easy to reproduce, I just ask that someone try it and see that this is still a problem.
