Codec used
Orig/Term call side indication
Snapshot of remote Gateway’s QoS at time of call connect
The calling and called numbers (with their corresponding IP addresses) are
just that, regardless of which end is doing the originating. So the Follower
card on the originating side generates a RADIUS record with its own IP
address as the originating IP address. The terminating Follower also
generates a RADIUS record with that far end’s IP address as the originating
IP address and its own IP address as the destination address.
If the call is not answeredor is rejected, only an End record is generated.
End record
The End record is sent when the call is released. It contains the following
fields:
Calling party number
Originating IP address and port
Called party number
Destination IP address and port (of the actual card handling the call, not
the remote Leader)
Call start time
Call duration (time from call answer to call release)
