Cisco Unified SIP Proxy Version
|
|
1.0 |
This command was introduced. |
Usage Guidelines
A listener is an interface, port, and transport tuple that the server listens on for incoming packets. Multiple listeners can be configured for a single server; however, at least one must be established for the server to accept SIP traffic. A network can have multiple listeners. You do not have to disable listeners on the network when you make configuration changes to the network.
Caution
You cannot run TCP and TLS listeners on the same port.
Caution
Do not enable the
sip listen command until you complete all of the other configuration tasks. After you enable the command, the system starts receiving incoming requests from the specified SIP network.
Examples
The following example configures the listener on a SIP network named “external” that uses the TCP:
se-10-1-0-0(cusp-config)> sip listen external tcp 10.2.3.4 5060
The following example configures the listener on a SIP network named “internal” that uses the UDP:
se-10-1-0-0(cusp-config)> sip listen internal udp 192.168.1.3 5061
The following example disables a listener on a SIP network:
se-10-1-0-0(cusp-config)> no sip listen external tcp 10.2.3.4 5060

Usage Guidelines
Record-routing ensures that all SIP messages within a dialog traverse the same route. The SIP Record-Route header field contains configurable interface, port, and transport values, which forces messages to pass through the desired SIP entity. The Record-Route feature is critical for directing messages to a load balancer that is managing SIP traffic for a group of servers.
Examples
The following example enables record-routing for a SIP network named “internal”:
se-10-1-0-0(cusp-config)> sip record-route internal udp cusp1.example.com
The following example enables record-routing for a SIP network named “external”:
se-10-1-0-0(cusp-config)> sip record-route external tcp 192.168.1.3 5061

To configure the value of the SIP Max-Forwards header field, use the sip max-forwards command in Cisco Unified SIP Proxy configuration mode. To remove the value from the SIP Max-Forwards header field and restore the default value, use the no form of this command.
sip max-forwards max_forward_value
no sip max-forwards max_forward_value
Syntax Description
max_forward_value |
Specifies the value of the Max-Forwards header field. The allowed values are 0 to 255. The default value is 70. |
Command Modes
Cisco Unified SIP Proxy configuration (cusp-config)
Command History
Cisco Unified SIP Proxy Version
|
|
1.0 |
This command was introduced. |
Usage Guidelines
The Max-Forwards header field of a SIP request specifies the maximum number of times the request can be forwarded to another server. Each time a request is received by a server, this value is decremented by one. (If the request does not have a Max-Forwards header, one is added.) When the value reaches zero, the server responds with a 483 (Too Many Hops) response and terminates the transaction.
You can use the Max-Forwards header field to detect forwarding loops within a network.
Note We recommend that you set this command to a value greater than or equal to 10, and less than or equal to 100.
Examples
The following example configures the value of the SIP Max-Forwards header field to 100:
se-10-1-0-0(cusp-config)> sip max-forwards 100

Command Modes
Cisco Unified SIP Proxy configuration (cusp-config)
Command History
Cisco Unified SIP Proxy Version
|
|
1.0 |
This command was introduced. |
Usage Guidelines
Use this command before configuring a SIP listener that uses the TLS transport.
Use this command to enable the use of SIP TLS connections with any other SIP entities, providing secure communications over the network. By default, TLS connections are accepted from all requesting clients with whom the Cisco Unified SIP Proxy has a trusted certificate. This is useful only when data encryption is desired and trust relationships are not required.
TLS encryption requires the two participating parties to specify a keystore and a corresponding trust certificate. When TLS is enabled, the system reads the key store files. As a result, before enabling the sip tls command, the keystore must first be created using the cypto key generate command.
Cisco Unified SIP Proxy supports both one-way and two-way TLS.
Note If there are active SIP listeners with the TLS transport enabled, then this command cannot be disabled.
Examples
The following example enables the use of SIP TLS connections:
se-10-1-0-0(cusp-config)> sip tls
The following example disables the use of SIP TLS connections:
se-10-1-0-0(cusp-config)> no sip tls

This command was introduced. |
Usage Guidelines
Use this command to provision a specific version or different versions of TLS. The default value is all TLS versions with fall-back.The connection between the user and the trusted peer fails to establish when the user tries to connect using the TLS version that the trusted peer does not support. In this case where the trusted peer does not support a specific TLS version, the user retries the connection with the trusted peer using the downgraded version of TLS. For example, if the trusted peer does not support TLS v1.2, then the user retries the connection using TLS v1.1.
Examples
The following example explains the use of SIP TLS to enable a TLS version:
se-10-1-0-0(cusp-config)> sip tls v1.0

route recursion
To enable SIP route recursion system-wide for the Cisco Unified SIP Proxy when a redirect response is issued, use the route recursion command in Cisco Unified SIP Proxy configuration mode. To disable SIP route recursion, use the no form of this command.
route recursion
no route recursion
Syntax Description
This command has no arguments or keywords.
Command Default
Route recursion is enabled by default.
Command Modes
Cisco Unified SIP Proxy configuration (cusp-config)
Command History
Cisco Unified SIP Proxy Version
|
|
1.0 |
This command was introduced. |
Usage Guidelines
When the Cisco Unified SIP Proxy receives a redirect response (that is, any 3xx response), it can be configured to recursively perform its routing logic on the received Contacts. A received Contact is placed into the Request URI of the prenormalized incoming request, and the server’s routing and postnormalization logic is executed based on the new destination. If multiple Contacts are received, they are processed sequentially based on their configured q-values. If more than one contacts have the same q-value, they are processed sequentially in order of the appearance. Use the command no route recursion in global configuration mode to turn off redirect processing in Cisco Unified SIP Proxy.
Examples
The following example enables route recursion on the Cisco Unified SIP Proxy:
se-10-1-0-0(cusp-config)> route recursion
The following example disables route recursion on the Cisco Unified SIP Proxy:
se-10-1-0-0(cusp-config)> no route recursion
