[Serusers] Race condition with CANCEL?

[Ingo Wolfsberger]

Hello,

Following situation:
t+0:
User A is registerd
User B is not registered

t+1:
User A calls user B
Call is transfered to the vm box.
vm does not go off-hook.

t+2:
User B registers

t+3:
User A hooks on, a CANCEL is send.

Currently I handle a CANCEL like an INVITE, which means the CANCEL is sent
to user B and not to the vm.

How to handle this case?

bye,
    Ingo
