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

[Jurijs Ivolga]

Hi Loi,

You can try to use uuid_setvar and set a variable for specific call.

https://freeswitch.org/confluence/display/FREESWITCH/Channel+Variables#ChannelVariables-AccessingChannelVariablesinOtherEnvironments

I hope this will help.

With kind regards,

Jurijs
