If you want to get as close to app_dial as you can:

1. Don't answer incoming channel
2. Originate outgoing channel
3. Watch events from outgoing channel
	If ringing then call /ring on caller
	If hung up then DELETE caller
4. Once outgoing channel has answered answer caller
5. Create bridge
6. Place caller and outgoing channel into bridge

If you want a simplistic dial then what you've done will work.
