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.
Information | Value |
---|---|
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.
Information | Value |
---|---|
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. To disable the access log maximum size and proxy access log settings, clear this control setting.
Information | Value |
---|---|
Data type | Boolean |
Default | Unchecked |
- Access log maximum size
- Specifies the maximum size, in megabytes (MB), of the access log
before it rolls over.
Information Value Range 1 to 65535 Data type Integer Default 20
- Proxy access log
- Specifies the location of the SIP proxy access log.
Information Value 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.
- 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.
Information Value 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.
Information Value 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.
Information Value 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.
Information Value 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.
Information Value 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.
Information Value Data type String Default None
- Tolerate a specific number of negative health checks
- Specifies whether to allow negative health checks.
Information Value 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.
Information Value 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. To disable the network outage detection, clear this sontrol setting.
Information | Value |
---|---|
Data type | Boolean |
Default | Unchecked |
- Keep alive interval
- Specifies the interval, in milliseconds, at which the KEEPALIVE
packets are sent to the SIP containers.
Information Value 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.
Information Value 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. To disable the maximum throughput and overload error response fields, clear this control setting.
Information | Value |
---|---|
Data type | Boolean |
Default | False |
- 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.
Information Value 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.
Information Value 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.
Information Value Data type String Default Service unavailable
