Signaling Timers

Each signaling protocol comes with a set of timers, one for each type of
message in the protocol. These timers determine when an expected
response to a message is overdue. They are set to the expected response
time when the message is sent and decrement towards zero. If they reach
zero before the response is received, the system is notified that the
response is overdue.
