[asterisk-dev] On ParkAndAnnounce and parking lot

[Sharath Chandra]

Thanks, Andrew.

I downloaded the latest branch as on today 27th March. I tried to access the
'PARKEDAT' variable in the following manner, but always the value of
${PARKEDAT} is displayed blank. Actually i want to access this variable when
dialed on another extension.
Can you give me some sample dialplan showing the usage.

Please advice.
