• To save settings click Submit.
• Changes will not be saved unless you click Apply Config in the upper right after clicking Submit.
• Multiple changes can be performed before Apply Config needs to be clicked.
• Ringtime Default timeout should be set to 30 seconds for best wakeup call results. This setting is under Settings | Advanced.

The DV2000 can use the same extension number for multiple lines which negates the need for any hunt groups and makes forwarding easier. All extensions used by the staff, rooms and the DV2000 should be configured the same. Configuration differences are the number of calls a single station can handle and where calls are forwarded.

The DV2000 can only currently change names via the configuration files. These name changes are not reflected in the UI currently. In order to support these types of name changes set config to Yes for both Read and Write. If this permission is not set then name changes will not occur.
