There are two kinds of DND, one is DND in device, another is DND in SIP server.
DND in device: It is a feature only for the device. When enable, the device can ignore any incoming direct IP/ SIP calls.
DND in SIP server: It is a feature only for a SIP account, it do not care which device register the SIP account. When enable, the device which is register the SIP account can ignore any incoming SIP calls.</fs></ff>

If the device register multiple SIP accounts, it can receive incoming SIP calls via other SIP accounts.


R2X only support DND in SIP server.

Account: To select which account to ignore any incoming calls.

Return Code when DND: Determine what response code should be sent back to server when there is an incoming call if DND is on.
DND On Code: The code is used to turn on DND on SIP server’s side, if configured, door phones will send a SIP message to server to turn on DND on SIP server side if users press DND when DND is off.
