[Freeswitch-users] Is Session.uuid the same as caller_profile/uuid in the cdr.xml?

Hiya, So my xml cdr has just one uuid in it. (I guess the shape and contents of this are configurable? But I'm using however it defaults.) cdr/callflow/caller_profile/uuid I wouldn't have thought caller_profile would be where I'd find a session.uuid, but since that seems to be the only uuid in the cdr, I'm guessing that's it if it's there. Is that it? I'm going to be logging the start of a phone call using the session uuid as the PK for a log record and need to be able to update that record later with call duration information when the CDR comes through after hangup.
