AudioCodes Mediant 1000B - Network Application Parameters

Version 7.2 1059 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
the Proxy Keep-Alive feature (EnableProxyKeepAlive parameter)
is enabled and its transport type is set to TCP or TLS. The device
first sends a SIP OPTION message to establish the TCP/TLS
connection and if it receives any SIP response, it continues
sending the CRLF keep-alive sequences.
configure voip > sip-definition
settings > ping-pong-keep-alive-
time
[PingPongKeepAliveTime]
Defines the periodic interval (in seconds) after which a “ping”
(double-CRLF) keep-alive is sent to a proxy/registrar, using the
CRLF Keep-Alive mechanism.
The default range is 5 to 2,000,000. The default is 120.
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
settings > 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 o
n 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 Registers interval
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.
