532.0 Configuring TalkSwitch
2.3.4.2 Prompted Call Back
If you are travelling to a location where you do not yet know the phone number,
you can use Prompted Call Back to save on your long distance charges. For details
on using Call Back, see section 3.7.2.
Number to call back:
This phone number should be entered exactly as you would normally have to dial
the number from this line (do not enter a Line Hunt Group in the dialing string).
TalkSwitch will Call Back out on the same line the call originated.
When you access Prompted Call Back from out of the office, you may change this
number before initiating Prompted Call Back. This is the benefit of Prompted Call Back
— you do not need to preset the number before you leave the office.
