Parameter
Description
■
[2]
Using REGISTER
= Enables the Proxy Keep-Alive feature
using SIP REGISTER messages. The device sends a
REGISTER message every user-defined interval, configured
by the SBCProxyRegistrationTime parameter. Any SIP
response from the proxy - success (200 OK) or failure (4xx
response) - is considered as if the proxy is "alive". If the proxy
does not respond to INVITE messages sent by the device, the
proxy is considered as down (offline). The device sends keep-
alive REGISTER messages only to one proxy. Only if the proxy
fails to respond to the keep-alive, does the device send the next
keep-alive REGISTER message to another proxy.
Note:
■
Proxy keep-alive using REGISTER messages (
Using
REGISTER
option) is applicable only to the Parking redundancy
mode ('Redundancy Mode' parameter configured to
Parking
).
■
If you enable this Proxy Keep-Alive feature, the device can
operate with multiple proxy servers (addresses) for redundancy
and load balancing (see the 'Proxy Load Balancing Method'
parameter).
■
For Survivability mode for User-type IP Groups, you must
enable this Proxy Keep-Alive feature.
■
If you enable this Proxy Keep-Alive feature and the proxy uses
the TCP/TLS transport type, you can enable CRLF Keep-Alive
feature, using the [UsePingPongKeepAlive] parameter.
■
If you enable proxy keep-alive using SIP OPTIONS messages
(
Using OPTIONS
), you can also enable the device to apply
various settings (e.g., SIP message manipulations) of the IP
Group that is associated with the Proxy Set , to these SIP
messages. For more information, see the 'Proxy Keep-Alive
using IP Group Settings' parameter in the IP Groups table.
'Proxy Keep-Alive Time'
proxy-keep-alive-
time
[ProxySet_
ProxyKeepAliveTime]
Defines the interval (in seconds) between keep-alive messages
sent by the device when the Proxy Keep-Alive feature is enabled
(see the 'Proxy Keep-Alive' parameter in this table).
The valid range is 5 to 2,000,000. The default is 60.
Note:
The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to
Using Options
.
'Keep-Alive Failure
Responses'
keepalive-fail-
resp
[ProxySet_
KeepAliveFailureResp]
Defines SIP response codes that if any is received in response to a
keep-alive message using SIP OPTIONS, the device considers the
proxy as down.
Up to three response codes can be configured, where each code is
separated by a comma (e.g., 407,404). By default, no response
code is defined. If no response code is configured, or if response
codes received are not those configured, the proxy is considered
"alive".
Note:
■
The SIP 200 response code is not supported for this feature.
■
The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to
Using OPTIONS
.
