DESCRIPTION
Specifies the length of time, in seconds, that the
phone waits until it re-attempts to register after a
REGISTER message times out.
If this parameter is set lower than 30 seconds, the
phone uses a minimum timer of 30 seconds.

SIP Settings (optional)" on
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.

Applicable for all event packages, this parameter
