Reg Retry Long Intvl (See
note below)
When registration fails with a SIP response code that
does not match<Retry Reg RSC>, the SPA9000 waits
for the specified length of time before retrying. If this
interval is 0, the SPA9000 stops trying. This value
should be much larger than the Reg Retry Intvl value,
which should not be 0.
Defaults to 1200.
Reg Retry Random Delay
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.
Defaults to blank, which disables this feature.
Reg Retry Long Random
Delay
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.
Defaults to blank, which disables this feature.
Reg Retry Intvl Cap
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.
Defaults to blank, which disables the exponential back-
off feature.
Sub Min Expires
This value sets the lower limit of the REGISTER expires
value returned from the Proxy server.
Sub Max Expires
This value sets the upper limit of the REGISTER min-
expires value returned from the Proxy server in the
Min-Expires header. Defaults to 7200.
Sub Retry Intvl
This value (in seconds) determines the retry interval
when the last Subscribe request fails. Defaults to 10.
