Among mobile service providers and indeed, general industry literature, there exists a known limitation of select prepaid platforms (as Nortel Service Builder(TM) for instance) and related prepaid network configuration(s) whereby prepaid subscribers are charged for airtime when incoming calls are forwarded to their voicemail boxes. The deficiency in the art is due to said platforms' inability to distinguish whether a call to a subscriber's mobile phone was in fact forwarded to the said mobile service provider/operator's voicemail system. The invention of present remains directed toward addressing the limitations and deficiencies of the existing art, and more generically to implementing a solution for re-crediting such incremental charges back to the said pre-paid wireless subscriber. Indeed, the method and system disclosed herein utilize said mobile service provider's existing infrastructure as well as existing telecommunications interfaces, protocols and the like. No modification to the provider's voicemail system, third-party proprietary prepaid platforms or other such matter is required.
