Misc. Dialplan Tools export
From FreeSWITCH Wiki
Exports a channel variable from the A leg to the B leg. Variables and their values will be replicated in any new channels created from the one export was called.
[edit]
Example
<action application="export" data="foo"/>
This typically also sets the A leg.
<action application="export" data="foo=bar"/>
To only export to the B leg, use 'nolocal:', like below:
<action application="export" data="nolocal:foo=bar"/>
