Canot transfer calls to the parking lot

I am unable to transfer calls to the parking lot, calls are hung up on rather than being parked. Below is a capture of what happens:

-- Called SIP/9797
-- Connected line update to SIP/acsip-0002e860 prevented.
-- SIP/9797-0002e861 is ringing
-- Connected line update to SIP/acsip-0002e860 prevented.

Any ideas?
