Abstract
In a messaging system, a messaging server transmits signals over the telephone network to be received by equipment at, e.g., the customer premises. Upon receiving a specific signal, the receiving equipment automatically signals the telephone network to connect the call, such as by going off-hook or by performing a hook flash sequence. In the connected state, the receiving equipment can receive data over the network, such as data to provide the recipient with notification information such as emergency notification messages.
