An apparatus, method and system are provided for an intermediate reliability protocol for network message transmission and reception, and are particularly suited for real time applications, such as internet telephony. The preferred system embodiment includes a plurality of servers, connected to each other over a plurality of networks, such as over two ethernets. A first server, when operative, includes program instructions to transmit a message. A second server, which is coupled to the first server over the networks, when operative, includes program instructions to receive the message. Under typical circumstances, the received message will be delivered locally on the second server, to a designated local process. Under other circumstances, the second server will resynchronize to the received message, dropping stored messages and avoiding further delay in message delivery. For such resynchronization, when the received message has a sequence number which is out of sequence, the second server has further instructions, first, to determine whether a reset bit is set and, when the reset bit is set, to resynchronize to the received message; second, to determine whether the first server is inactive and, when the first server is inactive, to resynchronize to the received message; and third, to determine whether a predetermined number of transmit reject messages have been transmitted to the first server and, when the predetermined number of transmit reject messages have been transmitted to the first server, to resynchronizc to the received message.

Calling party identification announcement service (CPIAS) provides an announcement of the caller's name to a called party, so that the called party may accept of reject a call. This invention relates to arrangements for providing CPIAS using centralized announcement synthesis apparatus, under the control of a data base (in accordance with the principles of intelligent networks), within the basic call processing arrangements of the public switched telephone network, without requiring users of the services to have two telephone numbers. Billing entries for the use of the announcement service are made under the control of the terminating switch so that these entries can be readily combined with other billing entries for the called party in order to generate a bill for that party.
