Mediant 500 MSBR
Where:

max-time is the value configured by MaxRegistrationBackoffTime

base-time is the value configured by RegistrationRetryTime
For example, if max-time is 1800 seconds and base-time is 30 seconds,
and there were three consecutive registration failures, then the upper-
bound wait time is the minimum of (1800, 30*(2^3)), which is (1800,
240) and thus, the minimum of the two values is 240 (seconds). The
actual time the device waits before retrying registration is computed by
a uniform random time between 50% and 100% of the upper-bound wait
time (e.g., for an upper-bound wait-time of 240, the actual wait-time is
between 120 and 240 seconds). As can be seen from the algorithm, the
upper-bound wait time can never exceed the value of the
MaxRegistrationBackoffTime parameter.
Registration Time
Threshold
configure voip > sip-
definition proxy-and-
registration > registration-
time-thres
[RegistrationTimeThresho
ld]
Defines a threshold (in seconds) for re-registration timing. If the
parameter is greater than 0, but lower than the computed re-registration
timing (according to the parameter RegistrationTimeDivider), the re-
registration timing is set to the following: timing set by the Registration
server in the SIP Expires header minus the value of the parameter
RegistrationTimeThreshold.
The valid range is 0 to 2,000,000. The default is 0.
Re-register On INVITE
Failure
configure voip > sip-
definition proxy-and-
registration > reg-on-
invite-fail
[RegisterOnInviteFailure]
Enables immediate re-registration if no response is received for an
INVITE request sent by the device.

[0] Disable (default)

[1] Enable = The device immediately expires its re-registration timer
and commences re-registration to the same Proxy upon any of the
following scenarios:

The response to an INVITE request is 407 (Proxy Authentication
Required) without an authentication header included.

The remote SIP UA abandons a call before the device has
received any provisional response (indicative of an outbound
proxy server failure).

The remote SIP UA abandons a call and the only provisional
response the device has received for the call is 100 Trying
(indicative of a home proxy server failure, i.e., the failure of a
proxy in the route after the outbound proxy).

The device terminates a call due to the expiration of RFC 3261
Timer B or due to the receipt of a 408 (Request Timeout)
response and the device has not received any provisional
response for the call (indicative of an outbound proxy server
failure).

The device terminates a call due to the receipt of a 408
(Request Timeout) response and the only provisional response
the device has received for the call is the 100 Trying provisional
response (indicative of a home proxy server failure).
Note: The parameter is applicable only to the Gateway application.
ReRegister On
Connection Failure
configure voip > sip-
definition settings > reg-
on-conn-failure
[ReRegisterOnConnection
Failure]
Enables the device to perform SIP re-registration upon TCP/TLS
connection failure.

[0] Disable (default)

[1] Enable
