Diameter Result Codes

The Diameter Result Codes presented on this page will be seen in one of two AVPs:

Diameter Base Application ID (0): Result-Code AVP      -or-      Vendor Specific Application Id (10415): Experimental-Result-Code AVP

The Vendor Id will be in the Vendor-Specific-Application-Id AVP.

For more information on Diameter messages and AVPs, refer to our Diameter Dictionary.
