There are a couple of ways to do this: 

1) if you have the 'ct' command, you can use it to dial out and start
up a gety task, you would then need a command like;
 (sleep 40 ; ct mynumber ) & 
 exit

40 seconds later, a ct run is started up..

2) write something like the following

	stty -hupcl -echo
	sleep 2
	echo  '+++\c' 
	sleep 2
	echo  'ATDT5551234\r\c'
	sleep 60
	stty echo
 It's possible to improve it by adding things like making it into
 a C program that can recognize a CONNECT/NO CARRIER etc. message
 and react appropriately, but I think the general Idea gets across.

 One serious problem with the shell script is that it leaves your
 system vulnerable to someone who manages to dial in between your
 hanging up and the system dialing out (you'd have a shell running
 at that point).
