3 Legs/call-ids Correlation Mapping about homer-app HOT 3 CLOSED

The X-CID is just a pointer to the previous originating SIP session and the concept mandates the same ID being propagated to fork legs. So the same A legs should produce the same X-CID in as many forks as the systems produces for correlation to work. They can cascade, as long as the chain keeps the links you can have as many forks you you want.

The mapping and correlation are note related to the number of legs. Just configure all the 1 to 1 relations (two rules for each method/header/etc) and they will be applied in a cascading fashion.

@lmangani Thank you, but I realize what is might my issue.

In my setup the X-CID is populated by the callid of the leg A but its changed every time the invite comes from a different server.

As i understand for the correlation to work in a cascading fashion, the x-cid should be populated by the call id of the leg between the phone and Sip server and should be transferred and the cid to be remained all the way to provider.
