When a call is established as an ICE direct media call, SBC does not support media handling. Therefore, the existing CDR fields are populated for Ingress and Egress local Ip address/ports as 255.255.255.255/65535 and Ingress and Egress remote IP address/ports as 127.0.0.0/5004 for each of the media streams on the call. For more information, refer to the section CDR Field Descriptions. |
