Abstract
A mobile terminal is provided with an access code for a destination receiving device. The access code specifies that the user terminal provide a communication signal through at least one communication network to the destination receiving device. The at least one communication network is assumed to have a capability of forwarding received communication signals that include access codes having a predetermined format to destination receiving devices. A determination as to whether a format of the access code provided to the user terminal differs from the predetermined format is performed. If these formats differ, another step includes modifying the format of the access code provided to the user terminal to produce a modified access code having the predetermined format in the communication signal.
