Testing from the cli:


freeswitch at internal> ftdm_usage 1 1
0
freeswitch at internal> eval ${ftdm_usage (1 1)}
-ERR invalid span

freeswitch at internal> eval ${ftdm_usage 1 1}
0

I think we need to drop the parenthesis?

Added this to the wiki for the next guy..



Also, is there a command to list all of the available commands from the cli? Something like ls 
/usr/bin would do for us in bash.

Or even a place in the source code that would list all the ftdi commands?

I'm getting things going - finding the learning curve steep in spite of having read all 3 books, but 
I'm getting old..

One thing that would be very useful would be some dialplan log command that would dump all the 
available variables to the cli - so you can at least know what you have to work with.
