Address digits for Precedence Calling

Last Updated : Oct 06, 2023 |

The address digits are the 7-digit or the 10-digit telephone number.

Precedence calls above the Routine level use special precedence ringback tones for the calling party, and a special ringing pattern for the called party.

On a Branch Gateway supported by S8300E, or a duplicated server, the gateway processor generates precedence calling tones.

  • The ringback tone is a 1.65-second burst of mixed 440-Hz and 480-Hz tone, and then 0.35 seconds of silence. This tone repeats until the call is answered, the caller hangs up, or the Precedence Call Timeout occurs. For more information, see Assigning Precedence Calling system parameters.

  • The ringing pattern for precedence calls is the same three-burst ring that is used with Priority Calling.
