SIP Timer H INVITE final response, time-out value, which can range from 0 to 64 seconds.
The default is 32 .
SIP Timer D ACK hang-around time, which can range from 0 to 64 seconds.
The default is 32 .
SIP Timer J Non-INVITE response hang-around time, which can range from 0 to 64
seconds.
The default is 32 .
INVITE Expires INVITE request Expires header value. If you enter 0, the Expires header is not
included in the request.
The default is 240 . Range: 0–(2
31
–1).
ReINVITE Expires ReINVITE request Expires header value. If you enter 0, the Expires header is
not included in the request.
The default is 30 . Range: 0–(2 31 –1).
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.
The default is 1 .
Reg Max Expires Maximum registration expiration time allowed from the proxy in the Min-
Expires header. If the value is larger than this setting, the maximum value is
used.
The default is 7200.
Reg Retry Intvl Interval to wait before the ATA device retries registration after failing during
the last registration.
The default is 30.
Reg Retry Long Intvl When registration fails with a SIP response code that does not match
Retry Reg RSC , the ATA device waits for the specified length of time before
retrying. If this interval is 0, the ATA device stops trying. This value should be
much larger than the Reg Retry Intvl value, which should not be 0.
The default is 1200 .
Reg Retry Random
Delay Random delay range (in seconds) to add to Register Retry Intvl when retrying
REGISTER after a failure.
The default is 0 , which disables this feature.
Reg Retry Long Random
Delay Random delay range (in seconds) to add to Register Retry Long Intvl when
retrying REGISTER after a failure.
The default is 0 , 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.
The default value is 0 , which disables the exponential back-off feature.
