[Freeswitch-users] Channel variables on a-leg and b-leg

[Vladyslav Zakhozhai]

Hi Paul,

${uuid} - is Unique Id of channel. For a-leg and b-leg it will be different
(I mean that uuid is not Call-ID). You can try to use call_uuid instead.
But I'm not sure about that.

I think that you can use set instead of export and fetch recording data
from a-leg. I'm using such approach and do not experience any problems with
that.
