[Freeswitch-users] Export all user vars to the b leg?

[Victor Chukalovskiy]

Good day, wondering if there is a one-liner method to export all 
user-specific variables to the b-leg of the call. I'm referring to all 
the vars I set within <variables> section of <user> in the directory.

I could've done it in the dialplan, but then I need to do it once for 
each var:
<action application="export" data="foo1=${foo1}"/>
.....
<action application="export" data="fooN=${fooN}"/>

Many thanks!
