Each Unwired Server instance relies on one or more Outbound Enablers (RSOEs) to manage its communications with Relay Server. Relay Server relies on the RSOE to initiate communications from an Unwired Server.
The RSOE opens outbound HTTPS connections to Relay Server, to handle both inbound and outbound communication channels, on behalf of the Unwired Server.
Each RSOE is an Unwired Server process, which manages communication on a particular Unwired Server client port — either the Messaging port, or the Replication port.
RSOE characteristics and behavior are defined by an XML configuration file. See System Administration, “System Reference” for details.
