Retry Reg RSC
Description
ReINVITE request Expires header value. If you enter 0, the
Expires header is not included in the request. Ranges from 0
to 2000000.
Defaults to 30.
Interval to wait before the conference phone retries
registration after failing during the last registration.
Defaults to 30.
When registration fails with a SIP response code that does not
match<Retry Reg RSC>, the conference phone waits for the
specified length of time before retrying. If this interval is 0,
the phone stops trying. This value should be much larger than
the Reg Retry Intvl value, which should not be 0.
Defaults to 1200.
Random delay range (in seconds) to add to <Register Retry
Intvl> when retrying REGISTER after a failure.
Defaults to 0.
Random delay range (in seconds) to add to <Register Retry
Long Intvl> when retrying REGISTER after a failure.
Defaults to 0.
The maximum value to cap the exponential back-off retry
delay (which starts at <Register Retry Intvl> and doubles on
every REGISTER retry after a failure). In other words, the
retry interval is always at <Register Retry Intvl> seconds after
a failure. If this feature is enabled, <Reg Retry Random
Delay> is added on top of the exponential back-off adjusted
delay value.
Defaults to 0.
Description
This parameter may be set to invoke failover upon receiving
specified response codes.
Defaults to blank
Interval to wait before the CP-8831-3PCC retries registration
