This is an old revision of the document! How do I divert a call ? You divert a call by connecting the number you wish to divert to an Extension block. The number you wish to divert to is set in the Extension block parameters Here's an example of number +441212123123 being diverted to Bob's mobile +447812341234 NOTE: numbers must always be entered in international format. TIP: The 'Call Announce' feature is useful for mobile diversion, it stops your mobile voicemail picking up the call and keeps control in the call flow.
