Virtual Extension Bug or Intentional?

Hello All,

I created a virtual extension 900 on FreePBX v 10.13.66-10, assigned it a number and outbound routes.
I then created a follow me list of a cell phone.
Saved, applied and then when we call it, we get a busy signal.
Did this a few times, played around with settings always resulting in the same issue.

I know this works, so I went to another server 6.12.65-32, created the same thing and it worked perfectly.

New Info:
Probably hadn’t updated in 3 weeks or so, ran an update and now that virtual extension when answered says “I’m Sorry” lol… I mean I have to be able to laugh about it.

You know the drill. Logs…
