IP Phone Release Notes 1.4.1

This section describes the features new to the IP phones in release 1.4.1. The 
features apply to all IP Phone models (480i, 480i CT, 9112i, and 9133i), unless 
specifically stated that only a particular IP phone model supports the feature.

The following table lists the new features in release 1.4.1. The paragraphs 
following this table describe each feature in detail.

 - 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.

 - 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.

 - In the Aastra Web UI only, the “registration retry 

timer” parameter name has changed to registration failed 

- 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.

An administrator can now enter a digit(s) at the end of the 
Local Dial Plan parameter string, which allows the IP phone 
to automatically add the digit as a prefix to a dialed number.
