  • When the subscriber’s phone is not contactable (eg, turned off or out of coverage)
  • Unconditional – also called an “all call” divert
  • Diverts are available for all subscribers
  • There is a divert known as DCF. This divert is one that is set by the network and is only called upon if no other diverts exist (hence the name default call forwarding).
