4.3Redial / Unredial

If B is on a call when A calls, A will get busy tone. If A wants to connect to B as soon as B is available, he can use the redial function. To use this feature, A dials a prefix and then B’s number.

When the redial function is activated, A will check B’s calling status every 60 seconds. When B is available, A’s phone will ring. When A goes off hook, the phone will call B automatically. If A does not want to call B, the redial function can be cancelled by dialing a prefix plus B’s number.

*3* is the redial prefix code. A can dial *3* plus B’s phone number to activate the redial function.

*4* is the unredial prefix code. A can dial *4* to cancel the redial function. The user can select any prefix as long as it does not interfere with dialing rules.
