Fixed Mobile Convergence - Mobility Extensions

Mobility Extension connects your mobile phone to your telephone system to 'twin' with your fixed extension allowing both phones to ring at the same time. If the call is answered on the mobile handset, up to 80% savings can be made over traditional diversion methods as the call is billed at mobile-to-mobile rates as opposed to landline-to-mobile rates. Calls can be transferred to another user or a conference initiated. In addition, a user can dial into the system from their mobile and make international calls via landline as opposed to having to pay expensive mobile costs.
