Cisco IP phones can use a RETRY-AFTER value when received from a SIP proxy
server that is too busy to process a request (503 Service Unavailable message). If
the response message includes a RETRY-AFTER header, the phone waits for the
specified length of time before retrying to REGISTER again. If a RETRY-AFTER
header is not present, the phone waits for the value specified in the Reg Retry
Interval or the Reg Retry Long Interval parameter.

To configure response status code handling:
Log in to the web administration interface.

tone is played. Reorder or Busy Tone is played by default for all
unsuccessful response status code for SIT 1 RSC through SIT 4 RSC.
Defaults to blank.
• Try Backup RSC—SIP response code that retries a backup server for the
current request. Defaults to blank.
• Retry Reg RSC—Interval the SPA9000 waits before re-trying registration
after a failed registration. Defaults to blank.
