Idle restart interval - The parameter sets the time in seconds between the restart of unused channels. The default setting is 3600. The minimum value is 60 seconds. Some PBXs do not like restarting for channels. As a solution, you can set a very large interval for them, for example: 100000000 or set the value never to completely disable the restarts of channels.
