Configuring a Server Blacklist Using the Aastra Web UI
You use the following procedure to configure Blacklist Duration using the Aastra
Web UI.
Aastra Web UI
1
Click on Advanced Settings->Global SIP->Advanced SIP Settings
2
In the “Blacklist Duration” field, specify the length of time, in seconds, that a failed server remains
on the server blacklist. The IP phone avoids sending a SIP message to a failed server (if another
server is available) for this amount of time. Valid values are 0 to 9999999. Default is 300 seconds (5
minutes).
For example: 600
Note: The value of “0” disables the blacklist feature.
