Mediant 800B Gateway & E-SBC
Parameter Description
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
[RegistrationTimeThreshold]
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 c
all 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
[ReRegisterOnConnectionFailure]
Enables the device to perform SIP re-registration upon TCP/TLS
connection failure.
 [0] Disable (default)
 [1] Enable
Gateway Registration Name
configure voip > sip-definition
settings > gw-registration-name
[GWRegistrationName]
Defines the user name that is used in the From and To headers in
SIP REGISTER messages. If no value is specified (default) for
the parameter, the UserName parameter is used instead.
Note:
 The parameter is applicable only to the Gateway application.
