Interactions for Precedence Routing

Last Updated : Dec 10, 2021 |

General

With Precedence Routing, calls with a precedence higher than Routine to terminate to:

  • Trunks

  • Telephones

  • Attendant consoles

  • Hunt groups

  • Recorded announcements

    Precedence Routing calls cannot terminate at Vector Directory Numbers (VDNs) or Terminating Extension Groups (TEGs).

Call Detail Recording (CDR)

No separate CDR field is supplied for the precedence level of a call. No separate CDR field creates an incompatibility between current call accounting software and the new call record format. With the current call record format, you can examine the call record for the Precedence Calling FAC to determine the precedence level of a call. If the call is a precedence call, the first digit of the number that was dialed indicates the precedence level of the call. If WNDP is active, you need to examine only the FAC because the precedence level is implied from the FAC. The CDR feature does not record the precedence level for a station-to-station call.

The cca-id field is the new CDR field related to MLPP. This field does not provide any information on precedence level of calls but shows the CCA ID of Communication Manager. The information displayed in the field comes from the MLPP form field: Call Control Agent Identification (CCA-ID).

CDR can be administered to record either the dialed digits or the outpulsed digits. In the case of Precedence Routing, the outpulsed digits can be different from the dialed digits. When you view CDR records, remember that the precedence level digit might not be recorded.

Chained Call Forwarding

Precedence routing works with call forwarding (one hop), however it is not supported with chained call forwarding (multiple hops).

Shortcut Dialing

When you use the Shortcut Dialing feature over DSN trunks, the system uses the Precedence Routing analysis tables to administer the incoming Shortcut Dialing digit analysis. The system does not use the ARS analysis tables.

Traveling Class Marks TCM)

Precedence Routing passes all TCM information over DSN and non-DSN trunks.
