MMTelInformation |
MmtelInformation |
The MMTel-Information AVP that will be written to a CDR, or sent in a Credit-Control-Request. This AVP is defined in 3GPP TS 32.299 v12.11.0 ยง7.2.111. Contains information about the MMTel supplementary services invoked during the call. |
Behaviour
The DiameterMMTelInfo feature populates the Diameter Ro MMTel-Information AVP with information about supplementary services used in the call. The feature stores an MMTel-Information AVP in session state, and updates it at various feature execution points when other supplementary services have run. The resulting MMTel-Information AVP is used by the VolteSipAvpCdr feature when writing a CDR. The MMTel-Information AVP is also sent in the final Credit-Control-Request to the OCS.
