What number (Caller ID) will be sent on calls I forward?

 Your sipgate phone number will be displayed on calls you forward.

The Caller ID of the person who called your sipgate basic phone number will not be shown on calls you forward from your sipgate account.

Can I change my forwarding so that the caller's number is displayed?

No, this option is not currently planned with sipgate basic residential.

Users of our sipgate team service can choose to display other non sipgate numbers on outbound calls.
