phone renews registrations. The phone will automatically
send registration renewals half-way through the registration
period, unless half-way is more than the threshold value.
For example, if the threshold value is set to 60 seconds and
if the registration period is 600 seconds, the renewal
REGISTER message will be sent 60 seconds prior to the
expiration, as half-way (600/2) > 60. If the registration
period was 100 seconds, then the renewal would be sent at
the half-way point as (100/2) < 60.
