Set a channel variable for the channel calling the application.
This application may be run [[Dialplan_XML#Inline_Actions|inline]] from the XML dialplan.
The variables will not be set until execution. If you need it right away in a condition, run it [[Dialplan_XML#Inline_Actions|inline]].
Setting multiple variables
To set multiple variables you can either call the set application multiple times or you can use the multiset application to set them all from a single line.
