How to setup SMS push notifications

What is UDP/IP?

UDP/IP (User Datagram Protocol/Internet Protocol) is a connectionless communication protocol used for transmitting data between devices across a network. It operates without the need to establish a connection, sending data in small units called datagrams, without guarantees of delivery, error checking, or retransmission if data is lost.

How do SMS push notifications work?

The diagram illustrates what happens when a chat user sends a new message. This message is routed through the on-premises Ozeki Chat Server, which acts as the central communication hub. The server processes the message and then sends push notifications directly to Windows and Macbook chat clients over the network using UDP/IP protocols. This enables immediate message delivery to desktop clients.

For mobile clients, including Android and iPhone devices, the Ozeki Chat Server uses the mobile network to send push notifications. This is facilitated by the SMPP (Short Message Peer-to-Peer) protocol, which communicates with the mobile network infrastructure. Push notifications to mobile devices are then delivered in the form of SMS messages.
