CHAPTER 60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
The device uses the range of 80-100% of this user-
defined value as the actual interval. For example, if the
parameter value is set to 200 sec, the interval used is
any random time between 160 to 200 seconds. This
prevents an “avalanche” of keep-alive by multiple SIP
UAs to a specific server.
'Max Generated Register Rate'
configure voip > sip-
definition proxy-and-
registration > max-gen-
reg-rate
[MaxGeneratedRegistersRate]
Defines the maximum number of user register requests
(REGISTER messages) that the device sends (to a
proxy or registrar server) at a user-defined rate
configured by the GeneratedRegistersInterval
parameter. The parameter is useful in that it may be
used to prevent an overload on the device's CPU
caused by sending many registration requests at a
given time.
The valid value is 30 to 300 register requests per
second. The default is 150.
For configuration examples, see the description of the
GeneratedRegistersInterval parameter.
'Generated Register Interval'
configure voip > sip-
definition proxy-and-

definition settings >
gen-reg-int
[GeneratedRegistersInterval]
Defines the rate (in seconds) at which the device sends
user register requests (REGISTER messages). The
parameter is based on the maximum number of
REGISTER messages that can be sent at this rate,
configured by the MaxGeneratedRegistersRate
parameter.
The valid value is 1 to 5. The default is 1.
Configuration examples:
■ If you configure the MaxGeneratedRegistersRate
parameter to 100 and the
GeneratedRegistersInterval to 5, the device sends a
maximum of 20 REGISTER messages per second
(i.e., 100 messages divided by 5 sec; 100 per 5
seconds).
■ If you configure the MaxGeneratedRegistersRate
parameter to 100 and the
GeneratedRegistersInterval to 1, the device sends a
maximum of a 100 REGISTER messages per
second.
configure voip > sip-
definition settings >
account-invite-failure-
trigger-codes
[AccountInviteFailureTriggerCodes]
Defines SIP response codes that if received for a failed
INVITE message sent for an Account, triggers the
device to re-register the Account. The parameter is
applicable only if the Account's 'Re-Register on Invite
Failure' parameter in the Accounts table is configured to
Enable (see Configuring Registration Accounts on
page 435).
The valid value is a SIP response code. Multiple
response codes can be configured, where each value is
separated by a comma. The default is "403,408,480"
(without quotation marks).
