Push messaging with curl is nice for broadcasting text messages to idle phones.

But if you've already got the caller on the phone, then you might consider the CONNECTEDLINE function in Asterisk...

	same => n,Set(CONNECTEDLINE(name)=User is Busy)

...sort of 'Reverse Caller ID Name' to immediately change what the caller sees on their phone display.

More involved is the CALLCOMPLETION function eg. for automating redials to the busy user when they hang up their call (see the ccss.conf.sample file.)
