Call forward to VM

Asterisk 11
FreePBX 2.11

Phone A calls Phone B, Phone B is Call Forward NA, Call Forward Busy to Phone C
B does not answer, it rolls call to C.
If C does not answer.
Phone A gets Phone C, VM not the original caller (Phone B).
How can I fix this?
I cant find any parameter in Voice Mail configuration

Any ideas?

Your description was somewhat obtuse, but I think you want a call to go to the VM of the original called number even if it has been forwarded elsewhere.

I’m not sure there is a way to do this simply by changing a setting or two.

Instead of using CF from B to C, configure phone B to use follow me instead. In the follow-me settings is an option to “confirm calls” which is what you want enabled so that the Phone C voicemail does not intercept the call.

I thought of that, but I don’t think confirm calls works on an internal call…
