To keep the implementation simple, only 1 timer is kept for the register 
condition and one for the subscribe condition. Since this timer may be 
servicing multiple registrations from the same NAT address, when one 
un-registers, the timer is not deleted to allow keeping the others alive. 
As a result it will keep sending keepalives until it expires, even if it 
has un-registered in the meanwhile.
