NOTE: - If the error response is any of 401, 407, 408, and 7xx, the exhibits the default characteristics even if the parameter is enabled.
- When this parameter is disabled (as the default behavior), and the gets an error response for the REFRESH REGISTER, it changes the RCB state from REFRESHING to TERMINATED and starts a 64 second timer.
- If the receives a Re-REGISTER request (REFRESH or UPDATE) within the next 64 seconds, it does not relay the request to the Registrar
and - .
- Instead, it locally responds to the UE with the previously preserved error message (because the RCB state is TERMINATED). However, if the receives an Un-REGISTER request from the UE within
the - 64 seconds, it deletes the information about the earlier registration failures
, - and allows the next REGISTER attempt to go through.
- When this parameter is enabled , on receiving and the receives an error response for REFRESH REGISTER attempts, the it sets the RCB state to COMPLETED instead of TERMINATED. On receiving subsequent REFRESH REGISTER requests, instead of locally relaying the previously stored error message to the UE, the the relays the REFRESH REGISTER request to the Registrar. In general, whenever the RCB is COMPLETED, the relays the REFRESH REGISTER requests to the Registrar.
