There's some vague security thinking behind a device who doesn't accept
any r-URI from, but only the registered contact. Is some cases, the
contact indicates a line or something in the device, so it needs the
full contact to be able to provide the user with the proper interface
reaction for the incoming call.
Yep. It's not stupid; the logic is quite clear, and the behaviour is
as intended. It just poses a problem for trunking and/or multiple DIDs
where the device is expected to potentially route a call differently
based on the number used to reach it.
