Systems and methods for sending and receiving text, or data, messages between wireless communication devices and wireline-messaging devices utilize a broadband connection to the wireline premises as the signaling channel. A message application server sends messages directly to wireline-messaging devices through a digital network, such as the Internet. Such systems and methods include wireline-messaging devices integrated with premises telephones connected to a PSTN, in which the telephones are adapted with thin client software to send and receive data messages.
