CONFIGURATION FILES
For the specific parameters you can set in the configuration files for setting Blacklist Duration,
see Appendix A, the section,
CONFIGURING A SERVER BLACKLIST USING THE MITEL WEB UI
You use the following procedure to configure Blacklist Duration using the Mitel Web UI.
MITEL 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.
3. Click Save Settings to save your changes.
