Ideally Fixed Mobile Convergence (FMC) creates a communications infrastructure that switches all calls centrally, both fixed and mobile, and delivers core telephony services to a business’s mobile users. The solution adds value for users and, with low support costs, delivers a sustainable positive impact on their business. Typically, this means moving minutes from the mobile network to the fixed network enabling a business to control, monitor and selectively decrease its mobile spend. Ideally, it also includes the provision of additional functionality to mobile handsets so that this functionality is available while out of the office and while roaming. Convergence marries together the best aspects of fixed and mobile services and simultaneously alleviates the negative associations of disparate telephony services. Convergence means access to new unified communications applications and traditional fixed-line services on the mobile handset, making internal and external communications more efficient and allowing employees to be more productive and responsive to customers.
