SIP proxy settings
The SIP proxy settings page contains general configuration items
that affect outbound transport configuration, toleration of IP Sprayer devices,
and access logging configuration.
To view this administrative console page, click proxy_server_name.
The SIP proxy settings panel allows you to define
attributes and policies that control the behavior of the SIP proxy server.
Default cluster
Specifies the default cluster name.
The Default cluster field must be set to a valid
cluster before any SIP messages are routed through the proxy server. The default
cluster indicates which cluster of application servers should receive SIP
traffic when there are no cluster selection rules defined, or when none of
the existing cluster selection rules match.
Data type |
Valid cluster name |
Default |
None |
Retry-after header value
Specifies the amount of time, in seconds, that the SIP proxy waits
before it returns the SIP request because the SIP containers are overloaded,
or the SIP proxy cannot locate available servers to which it can route the
request.
Range |
1 to 1000 |
Data type |
Integer |
Default |
5 |
Logging
Specifies whether to enable or disable access logging.
When Enable access logging is checked, specifies
the access log maximum size and proxy access log path name. When this control
is unchecked, access log maximum size and proxy access log settings are disabled.
Data type |
Boolean |
Default |
Unchecked |
- Access log maximum size
- Specifies the maximum size, in megabytes (MB), of the access log before
it rolls over.
Range |
1 to 65535 |
Data type |
Integer |
Default |
20 |
- Proxy access log
- Specifies the location of the SIP proxy access log.
Range |
Valid path name |
Data type |
String |
Default |
$(SERVER_LOG_ROOT)/sipproxy.log |
Container facing network interface
This section contains fields that configure the container-facing
network interfaces.
Note: The value asterisk (*) means let the OS decide which interface to use.
- UDP interface
- Specifies the network interface for all User Datagram Protocol (UDP) data
that goes to and from the SIP container. The value for this setting is the
hostname or IP address to use for all communications between the SIP proxy
and the SIP containers when the network is segmented.
Note: If a value is specified for this setting, you must also specify
a value for the UDP port setting.
Data type |
String |
Default |
* |
- UDP port
- Specifies the UDP port for SIP container communications, such as the specific
port required to pass through a firewall that separates the SIP proxy and
the SIP containers.
Note: If a value is specified for this setting, you must
also specify a value for the UDP interface.
Range |
1 to 65535 |
Data type |
Integer |
Default |
* |
- TCP interface
- Specifies the network interface for all Transmission Control Protocol
(TCP) data that goes to and from the SIP container or containers.
Data type |
String |
Default |
* |
- TLS interface
- Specifies the network interface for all Transport Layer Security (TLS)
data that goes to and from the SIP container or containers.
Data type |
String |
Default |
* |
Load balancer health checking
This section contains fields that configure the load balancer used
to load balance the SIP proxy server and perform health checks.
- Load balancer members (IP address 1 and 2)
- Specifies the IP addresses of the load balancers that source the SIP health
checks. The IP addresses (1 and 2) ensure that the message is an actual SIP
advisor request before sending a response back to it.
Data type |
String |
Default |
None |
- SIP health check method name
- Specifies the health check method name sent to the SIP proxy from the
load balancer.
Data type |
String |
Default |
None |
- Tolerate a specific number of negative health checks
- Specifies whether to allow negative health checks.
Data type |
Boolean |
Default |
False |
- Maximum negative health checks
- Specifies the number of SIP health checks that the load balancer can perform
that return negative results, indicating that there is a communication problem
between the load balancer and the SIP proxy, before this SIP proxy informs
the other SIP proxies that it is no longer processing data.
Range |
1 through 10 |
Data type |
Integer |
Default |
3 |
SIP network outage detection
Specifies whether to enable or disable outage detection.
When Enable SIP network outage detection is checked,
specifies the KEEPALIVE interval and maximum KEEPALIVE failures. When this
control is unchecked, network outage detection is disabled.
Data type |
Boolean |
Default |
Unchecked |
- Keep alive interval
- Specifies the interval, in milliseconds, at which the KEEPALIVE packets
are sent to the SIP containers.
Range |
1 through 1000 |
Data type |
Integer |
Default |
3000 |
- Maximum keep alive failures
- Specifies the number of KEEPALIVE requests that are sent without getting
a response before considering this server down.
Range |
1 through 10 |
Data type |
Integer |
Default |
3 |
Overload protection
Specifies whether to enable or disable overload protection.
When Enable proxy managed overload protection is
checked, specifies the maximum throughput allowed and overload error response.
When this control is unchecked, maximum throughput and overload error response
fields are disabled.
Data type |
Boolean |
Default |
True |
- Max throughput factor
- Specifies the degree of overload protection at the proxy and is a percentage
of the maximum messages per averaging period for the SIP container.
Range |
1 through 100 |
Data type |
Integer |
Default |
90 |
- Overload response code
- Specifies the overload response code. When the proxy detects an overload
condition, it will respond to the request with the overload response code,
if it is set.
Data type |
Integer |
Default |
503 |
- Overload response reason
- Specifies the overload response reason phrase. When the proxy detects
an overload condition, it will respond to the request with the overload response
phrase, if it is set.
Data type |
String |
Default |
