Q: Do you have the configuration for VVX300 to disable the Do Not Disturb key? The configuration for the VVX500 does not work.

A: Please downgrade the VVX300 to 4.1.8 and search for this line: 

  <?xml version=”1.0″ standalone=”yes”?>

                <!– Customer SIP Application Configuration File –>


                <serverMissedCall call.serverMissedCall.1.enabled=”1″/>

                <dnd feature.enhancedFeatureKeys.enabled=”1″ softkey.feature.doNotDisturb=”0″ />.
