[Freeswitch-users] Is there equivalent of "last_bridge_to" but showing "last_originated_leg"

[Victor Chukalovskiy]

Good day,

My ultimate goal is for any given a-leg CDR to find the very last b-leg CDR.

var "last_bridge_to" allows to find last b-leg for any given a-leg as 
long as call was actually "bridged". However, if given a-leg had b-leg 
originated, but no actual media or ring-back happened, variable 
"last_bridge_to" remains empty. So I can't use that.

So is there a single variable on a-leg CDR that contains UUID of the 
last "originated" leg?

I know there are arrays e.g. "originated_legs" or "originate_causes", so 
worst case scenario I can iterate and pick the last UUID in either one 
of these arrays. But this means external code or fancy trigger functions 
upon CDR SQL insert. Trying to avoid that.

Many thanks!
