[Asterisk-Users] .call file creation

[Dan Adams]

I am curious partly because it has occurred randomly in my asterisk 
system. How does one go about creating a .call file for placing a call 
between two extensions/phones? I know this has been mentioned and is 
probably in one of the wikis somewhere, but I am unsure exactally how to 
go about doing it. Can anyone point me in the right direction.
