Chan.control

This message is used to apply various operations and parameter changes to existing channels or components.

Parameters

id of the channel to control

component

Optional parameters

Each channel and component supports various optional parameters depending on its type.

operation

Note

• This message can be generated by the rmanager command control, in that case targetid and component are set to the same value.
• SS7 components can be controlled at runtime by specific commands.
• The client also uses this message for volume control.
• If the message is generated from rmanager, chan.control will succeed if the requested component is found, even if the requested operation failed to be executed.

rmanager control return status messages

   - Could not control COMMAND; If the target component is not found
   - Control 'COMPONENT_NAME' FAILED; if the component with COMPONENT_NAME is found but failed to execute the requested operation.
   - Control 'COMPONENT_NAME' OK; if the component with COMPONENT_NAME is found and the requested operation succeeded.
