Reroute On Answer

Reroute On Answer allows configuration of rerouting scenarios based on the Application ID and Result-Code AVP values in Answer messages. If the values in the message match a configured order pair of Application ID and Result-Code AVP values, the message can be rerouted to another available connection or Peer Node from the Peer Route Group selected during the routing process.

If there are no additional available Peer Nodes in the selected Route Group, or the maximum number of transmits has been met, then reroute is not attempted and the Answer is sent back to the originator.

Diameter configuration for each Reroute on Answer Result-Code AVP:
  1. On the Diameter Configuration Reroute On Answer GUI,
    1. Enter the Answer Result-Code AVP Value.
    2. If Reroute On Answer is to be triggered by a specific Application Id and Result-Code AVP pair, select the Application Id for the specified AVP.
    3. If Reroute On Answer is to be triggered for all available Application Ids for a Result-Code AVP, do not select an Application Id.
  2. Configure Peer Nodes.
    1. Alternate Routing on Answer Timeout
      • Select Same Peer to perform alternate routing on alternate connections on the same Peer before selecting the next eligible Peer in the Peer Route Group.
      • Select Same Connection perform alternate routing on the same connection on the same Peer before selecting the next eligible Peer in the Peer Route Group.
      • Select Different Peer to perform routing on a different Peer in the Peer Route Group.
    2. Alternate Routing on Answer Result Code
      • Select Same Peer to perform alternate routing on alternate connections on the same Peer before selecting the next eligible Peer in a Peer Route Group when a Reroute on Answer Result Code occurs.
      • Select Different Peer to perform routing on different Peer in the Peer Route Group.
  3. Configure Route Groups as Peer Route Groups (not Connection Route Groups).
  4. Configure Pending Answer Timers

    A Pending Answer Timer can be configured and assigned to each Application Id and Peer Node. The timer expiration can be used to trigger Reroute on Answer rerouting of a message.
