How does conditional forwarding work?
Mobile carriers accept standard GSM codes that forward a call to another number under certain conditions. For example, **61*number# forwards when you do not answer, **62*number# when the phone is unreachable, and **67*number# when you are already on a call. With CallReply, that number is the CallReply voicemail. Your line stays the same, customers still dial your usual number, and only the calls you do not take are redirected. You can turn forwarding off at any time with the matching cancel code.
