Edit one VDN or a group of VDNs. When you edit VDN configuration, you cannot modify the VDN extension. If you want to use a different VDN extension, you must duplicate the required VDN configuration or add a new VDN.
When you edit a group of VDNs, the Name and Music Source fields are unavailable for editing. To modify these fields, you must edit each VDN configuration separately.
