Description (partial)

Symptom:
s per RFC, when the gateway sends a registermessage with expiration time 60 (normal operation) and receives a response 200 OK with expiry time 0, then the gateway should send a new register immediately with the predefined expiration time (60).

However, we observe that the gateway does not send a registration message immediately but waits instead for the expiation time to be elapsed in order to send another registration message.

Please also note that provisional response 200 OK with expiration time 0 can also be received in case of de-registration. The difference in that case is that the gateway sends at first place a register message with expiration time 0

Conditions:
When CUBE receives a 200 OK with expires = 0
