Analog terminal internet access

A centralized messaging system for use with a switched telephone network having central office switching systems connected in a voice network by trunks, subscriber lines connected to central office switching systems, a Common Channel Interoffice Signaling (CCIS) network for establishing routing of calls through the trunks and lines, and a service control point connected to said CCIS network for data message communication over the CCIS network, said centralized messaging system comprising:

• storage means for storing messages receivable from or deliverable to said switched telephone network;
• a first interface for connection to said voice network;
• a second interface for connection to a dedicated private data network linked to said service control point;
• an Internet interface for connection to the public Internet using transmission protocols to provide packet delivery service via the public Internet;
• and
• multiple selectable protocol conversion modules capable of different conversions for accepting message inputs of multiple protocols and providing outputs of varying protocols;
• wherein said conversion modules are selectable in response to signals received from the switched telephone network and originated by a telephone station connected to a subscriber line in the network.
