Note The phone can use a RETRY-AFTER value when it is 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 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.
