please note that a client wants to have the following:
When a user is not logged in on his device using extension mobility, he will be able to receive a call on his extension 100 for instance but not calling.
when he is logged in, he can call and revceive on the same extension which is 100.
i am thinking of having 100 with no access on the extension mobility profile and forward no register to 101 another extension where he is logged out.
any better idea?
