Registration Renewal Timer	sip registration renewal timer	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 registra-
		tion 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.
		For more information, see Chapter 4, “Advanced SIP Settings (optional)” on
		page 4-69.
