There are two ways... 1) Use the Limit functionality. This only works if you're the only person sending calls, since you can only count your own calls. http://wiki.freeswitch.org/wiki/Limit 2) Send the call to the user, and see if they reject the call with 486 Busy Here if busy. Simply handle that hangup reason. This will work if they are receiving a call from other users, but doesn't work with all phones - eg some will have multiple lines so allow a call to ring even if they've already answered another call.

Hi,

I would like to implement in my biling function that the FS will do call fwd if user is busy.

How can I detect user busy? I am doing dialplan with curl.
