Setting Call Precedence with a Digit Map

To set call precedence you can configure a digit map in a dial plan or you can set precedence directly on the server using a number prefix and a namespace. If you enable MLPP and don’t configure a precedence level to a number, the phone sends the call at the default precedence level.

Example

dialplan.digitmap=3xxxTP4|4xxxTP5

All digits matching the pattern 3xxxTP4 and 4xxxTP5 are sent with precedence 4 and 5 respectively. In this example:

  • If the user dials 3434 the call is sent with precedence 4. If the user dials 3345 the call is sent with precedence 4.
  • If the user dials 4666 the call is sent with precedence 5.

If the dialed number doesn’t match any number, then the default precedence is sent based on the value you set with voIpProt.SIP.assuredService.defaultPriority, default value 1.
