WCTP is a simple way for delivering wireless messages, both one and two-way, to appropriate receiving devices such as pagers and cellular phones. In its simplest form, WCTP provides a simple way to implement a "shim" between the Internet and a TAP/IXO paging terminal. It also has the ability of receiving end-to-end acknowledgments and replies from a two-way messaging device such as ReFLEX units.
Gateways supporting this protocol are now emerging as this is a new protocol. Commercial companies such as American Messaging and USA Mobility, and private businesses as well. A list of companies that currently have WCTP Gateways can be found here.
