How to Configure Priority Calls

How to Configure Priority Calls


Normally when you put your extension into Do Not Disturb status with the built in DND feature code the default caller behavior is to forward that caller to your voicemail.  Previously you could also create a custom call forward rule for all DND calls.  But a caller could never bypass Do Not Disturb completely.

The administrator can define a custom feature code for 'Priority Call' in the ScopTEL Features Code section and the end user extension can use the feature code to whitelist and blacklist any callerid number they wish.  Once the feature code is used and a number is whitelisted the DND rule will be ignored and any configured call forwarding rule will be honoured.

By example an executive wants to put their phone into DND but allow their executive assistant to transfer important calls to their extension.


Add the Priority Call Feature code to the extension's applied Class of Service

Executive extension =250

Executive Assistant extension =230

The Features Code section 'Priority Call' Feature Code is defined as *68

The Executive dials *68230 which immediately adds callerid 230 to extension 250's whitelist.

Now extension 250 will ring or receive a transferred call from extension 230

To remove the extension from the whitelist the executive dials *68230

The process can be repeated to add or remove many callerid numbers to the whitelist.


Priority Call works for attended and blind SIP transfers only, DTMF transfer codes are not supported.

SIP DND Cause Codes are not supported you must use Server based Do Not Disturb Feature Codes.
