The threshold value, in seconds, prior to expiration, that the 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.
