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
(see Note below)
Interval to wait before the Cisco IP phone retries registration after
failing during the previous registration. Do not enter 0. Defaults to
30 seconds.
Reg Retry Long
Intvl
(see Note below)
When registration fails with a SIP response code that does not
match the Retry Reg response status code (RSC) value (see next
table), the Cisco IP phone waits for this length of time before
retrying.
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.
