I have a question about call forwarding and availability of "dialed

> Some user has set up his/her phone (with number A) to forward "all"

As they say "it depends." Normally in forwarding/diverting situations the original number will show in the call display of the end party and not the number that it's being forwarded/diverted from. If the number it's being forwarded/diverted is a toll-free number it may "destroy" forwarding or it may keep it intact. When I use my "Kall8"

number to forward to another number the original number is presented to the end party's caller ID display. I have an option with my toll-free number that I can have either the "real" number presented or the toll-free number presented to the end party's display.
