You can also add * and # for bridge prompts.
It's very cool how this works too. If you put in a phone number/passcode/initiator codes in the phone number field, it will do them all for you. But - keep an eye on the keypad. To the right of the "End" button, a "dial" button will appear - this allows you to initiate the bridge entries automatically!
The cool thing is that the bridge number will dial normally otherwise, so that as in the case with my work, I can call someone else's bridge with different pass codes than the one I have stored.

Example:
1 (866) 555-1212,123456#,987654#,1

This dials my bridge, enters the passcode, then my initiator pin, and starts the call. Beautiful!

If I just want to call the bridge for someone else's call, I hit the same Contact, and it only dials:
1 (866) 555-1212

Well done, if not entirely hidden from users.

What are "bridge prompts"?
