I have a weird problem on one of the CME systems that we manage. When reception transfers an outside call to an internal extension the call goes to the hunt group that is set as CFBusy on that line. This is when the phone is completely idle. This happens on many (all?) extensions but you can ring the extension direct. This has only started happening since a reload the other day caused by a power failure. Transfer-pattern .T is configured.
Call scenario -
Incoming call -> reception x200
200 consultative transfers call to 202 (which is idle)
200 sees call going to 380 (huntgroup configured as CFBusy on 200 which is CFBusy on 202)
380 rings 216.
I've tried rebuilding cnf-files and resetting phones but I cannot see any reason why these phones are showing as busy when they're not.
