Forwarding calls
There are a number of situations when you may want to forward incoming calls to another number or to voicemail.
You can set up call forwarding for the following situations:
Feature |
Action |
---|---|
Forward all calls |
Forwards any call to another number |
Forward when busy |
Forwards calls to another number when you're busy on a call or if you have activated another service that blocks incoming calls, for example, do not disturb |
Forward when unanswered |
Forwards calls to another number if you don't answer before the number of rings that you set as the limit |
Forward when unreachable |
Forwards calls to another number if technical problems prevent One Net from connecting a call to your phone |
Forward selected calls |
Forwards calls to another number if a call meets the criteria you have specified in one or more rules |
You can also forward calls to voicemail all the time, when you're busy or when you're unable to answer the phone. If you set up call forwarding to both another number and to voicemail for the same situation, for example when your phone is busy, it will be forwarded to the phone number rather than voicemail.
