Abstract
Apparatus and method for management of optimal voicemail deposit to the voicemail of a currently roaming mobile telephony user during late call forwarding, is located at the user'"'"'s home network and includes a disconnection unit for disconnecting an international link upon detection of late call forwarding; a triggering unit that ensures that a trigger signal is available for triggering the passing of control of the call to allow direct forwarding of the caller to the voicemail; and a direct forwarding unit that receives the control and carries out the forwarding. Generally the roaming user only generates a single trigger, and this causes difficulties if multiple services need triggering for the same call, such as a prepaid unit and the optimal voicemail deposit. The disclosure teaches methods which when used in combination provide a system that can operate at the home network irrespective of the configuration of the roaming network.
