proxy in the Min-Expires header. If the value is larger
than this setting, the maximum value is used.
Defaults to 7200.
Interval to wait before the SPA9x2 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 SPA9x2 waits for
the specified length of time before retrying. If this
interval is 0, the SPA9x2 stops trying. This value should
be much larger than the Reg Retry Intvl value, which
should not be 0.
Defaults to 1200.
