Call divert is a�handset feature that allows the user to forward or redirect all incoming calls to an alternate�number (fixed or mobile), or to voicemail. This is a facility with many advantages, enabling the user to be called on another phone or at a particular location, to have calls answered by somebody else, or to use a voicemail answering service. When this feature is activated the�number from which calls are forwarded will not ring or receive calls. Various options may be available to the user, allowing them to choose different phone numbers to divert to, depending on the circumstances. For example, calls may be diverted to one number when engaged (busy transfer), but another number or voicemail when the phone is switched off or the network unavailable.
