In a mobile telephone system, a call routing equipment such as an SMS Router (18) receives a routing information request signal (SRI_SM) indicative of a communication such as a text message intended for a mobile terminal (10), and returns a routing information response signal (False Response) indicative of the SMS Router (18) instead of being indicative of the intended mobile terminal (10). This allows processing (Copy sent via TCP/IP) of the resulting text message (MTForwardSM) by the SMS Router (18), such as archiving of the text message, sending the text message to an email address, and/or forwarding the text message to an alternative destination.
