All Models
SIP Timers The following are SIP timers that were added or changed
on the IP phones:
SIP Registration Renewal Timer - A new parameter called sip
registration renewal timer has been added that allows an
administrator to control when the phone renews SIP
registrations. Configurable via configuration files and Aastra
Web UI.
SIP Registration Timeout Retry Timer - An administrator can
now set the time, in seconds, that the phone waits until it
attempts to register the phone after a REGISTER message
times outs. This new parameter is called sip registration
timeout retry timer. Configurable via configuration files and
Aastra Web UI.
“SIP Registration Retry Timer” Web UI Parameter Name
Change - In the Aastra Web UI only, the “registration retry
timer” parameter name has changed to registration failed
retry timer.
Explicit Message Waiting Indicator (MWI) Subscription Period
- An administration can now set the length of time, in
seconds, of an explicit MWI subscription. This value allows
the phone to re-subscribe the explicit MWI subscription
before the timeout value is reached.
