There are two methods for modifying user configuration parameters:
Edit the user configuration files and modify configuration parameters.
Issue the dmctl command to temporarily modify configuration parameters when VoIP Availability Manager is running.
Some configuration changes can only be made by modifying the parameter settings in the configuration files and then restarting VoIP Availability Manager. Every time that VoIP Availability Manager starts, it sets its configurations in accordance to the settings in the user (and other) configuration files.
