Correct me anybody if I'm wrong; but I think this way he will only free
his internal extension not the PSTN line.
I think the only way of doing this is to order call forward feature form
his PSTN service provider, so when the call comes and his number is busy
it will automatically redirect it to let say DID number over IP (or any
other number).
