Aastra Telecom 41-001343-02 用户手册

Parameter – 
sip registration renewal timer

Configuration Files
aastra.cfg, <model>.cfg, <mac>.cfg

The threshold value, in seconds, prior to expiration, that the phone renews registrations. 
The phone will automatically send registration renewals half-way through the registra-
tion 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 expira-
tion, 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.
