Response Status Code Handling
NOTE: 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.
Parameter Description

Information Tone (SIT). For example, if you set the SIT1
RSC to 404, when the user makes a call and a failure
