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.

This behavior is available since revision 5396.
