[Freeswitch-users] How to export variable downstream on execute_on_answer?

Fri Aug 11 08:02:20 UTC 2017

Hi Jurijs, your answer really helps, thanks a lot.
My problem is solved with below call from the dialplan got executed on
answer.

*${uuid_setvar(${signal_bond} myvar ${sip_rh_X-MyVar})}*

And btw, I find an alternative way in the meantime with using
*bridge_export* instead of

*export.*
rgds,
Loi Dang
