Use the API command "create_uuid" to create a uuid for the call (on the first server that handled the call on your side). Pass the uuid to each server along the way via a sip header. Leave the uuid's that are generated for each session; you'll need it. Links below.

Any suggestions for adding a unique identifier to a call to be able to track it across multiple servers when tracing a call path?
