Interval to wait before the 900 Series phone retries registration after failing during
the last registration.
The default is 30.
When registration fails with a SIP response code that does not match<Retry Reg
RSC>, the 900 Series phone waits for the specified length of time before retrying.
If this interval is 0, the 900 Series phone stops trying. This value should be much
larger than the Reg Retry Intvl value, which should not be 0.
The default is 1200.
This value sets the lower limit of the REGISTER expires value returned from the
Proxy server.
This value sets the upper limit of the REGISTER min-expires value returned from
the Proxy server in a Min-Expires header
This value (in seconds) determines the retry interval when the last Subscribe
request fails.
Random delay range (in seconds) to add to <Register Retry Intvl> when retrying
REGISTER after a failure. This feature was added in Release 5.1.
The default is 0, which disables this feature.
Random delay range (in seconds) to add to <Register Retry Long Intvl> when
retrying REGSITER after a failure. This feature was added in Release 5.1.
The default is 0, which disables this feature.
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. This feature was added in Release
5.1.
The default value is 0, which disables the exponential back-off feature.
