Reg Min Expires Minimum registration expiration time allowed from the proxy in
the Expires header or as a Contact header parameter. If the proxy
returns a value less than this setting, the minimum value is used.
Defaults to 1 second.
Reg Max Expires Maximum registration expiration time allowed from the proxy in
the Min-Expires header. If the value is greater than this setting, the
maximum value is used.
Defaults to 7200 seconds.
Reg Retry Intvl Interval to wait before the Cisco IP phone retries registration after
failing during the previous registration. Do not enter 0. Defaults to
(see Note below)
30 seconds.
Reg Retry Long When registration fails with a SIP response code that does not
Intvl match the Retry Reg response status code (RSC) value (see next
table), the SPA9000 waits for this length of time before retrying.
(see Note below)
If this interval is 0, the Cisco IP phone stops trying. This value
should be much larger than the Reg Retry Intvl value. Defaults to
1200 seconds.
