[Freeswitch-users] event BACKGROUND too late in ORIGINATE scenario?

[UV]

We're busy integrating a heavy-duty call-control engine on top of the
Freeswitch and I'm not sure if what's happening is by design or a bug:

When originating a call via the "bgapi originate" call (mod_commands) the
BACKGROUND event invoked only AFTER the call successfully terminated
(answered/rejected). 
Because only the BACKGROUND event has the correlation between the JOB-UUID
of the BGAPI command and the UNIQUE-ID, it's impossible to intercept all the
events until that point (create, outgoing, ring, codec-exchange, etc).

This becomes a real problem when originating multiple calls in a short time.
It's impossible to distinguish which event belongs to which origination
request. Resorting to pull that info from the DB or through SHOW CHANNELS
might still cost missing few events.

Anyone has any ideas on how to track an ORIGINATE call setup flow?


Here's an extract from the log (just took the relevant parts):
