A communication channel is the conduit for receiving inbound and delivering outbound messages.
Short Message Peer-to-Peer (SMPP) – connections are used to send and receive SMS messages.
The platform administrator can configure SMPP (inbound and outbound) and JMS channels to have one or more connections, and set these connections to active or inactive. An active connection on an inbound channel receives incoming messages. An active connection on an outbound channel delivers outgoing messages. Channels are defined at the platform level, and are shared by all workspaces.
