A SIP network is a logical collection of local interfaces that can be treated the same for general routing purposes.
Procedure
Step 1 Choose Configure > Networks.
The system displays the Networks page, listing all of the current networks.

Adding a Network
Restriction
After a SIP network is created, you cannot remove it.
Procedure
Step 1 Choose Configure > Networks.
The system displays the Networks page.
Step 2 Click Add.
The system displays the Network page.
Step 3 Enter the following information for the network:
|
|
Name |
Contains a name for this network. Network names can contain alphanumeric characters, period, dash, and underscore.
Tip You cannot rename networks, so choose the network name carefully.
|
Type |
Can be one of the following:
- standard—Configures the network interface to use standard SIP. The network has full UDP support. The network interface supports ICMP and different sockets can be used for each endpoint.
- icmp—Configures the network interface to use Internet Control Message Protocol (ICMP).
- noicmp—Specifies that the network interface does not use a separate socket for each endpoint. With this configuration, no ICMP errors are supported.
- nat—Configures the network interface to use Network Address Translation (NAT).
|
Allow Outbound Connections |
Determines if you will allow this network to enable or disable outbound TCP/TLS client connections. Can be either enable or disable. Default value is enable. |
SIP Header Hiding: Hide VIA |
Check this check box to have the system strip the VIA header, so that downstream elements will not know the message path. |
UDP Settings: Maximum Packet Size |
Configures the maximum size of a UDP datagram for this network. The value must be between 1500 and 16,000. |
Step 4 Click Add.
The system displays the Networks page with all the networks listed, including the network that you just added.
Step 5 To add a SIP Listen Point, do the following:
a. Under the SIP Listen Points heading, click click here on the line for your network.
b. Click Add.
c. Enter the following required values:
– IP address for the SIP Listen Point
– Port for the SIP Listen Point
– Transport type (UDP, TCP, or TLS) for the SIP Listen Point
d. Click Add.
Step 6 In the Cisco Unified SIP Proxy header, click Commit Candidate Configuration to commit this change.

|
|
T1 |
Sets the initial request retransmission interval. |
T2 |
Sets the maximum request retransmission value. |
T4 |
Sets the amount of time a NONINVITE client transaction or INVITE server transaction remains active after completion to handle request or response retransmissions. |
TU1 |
Sets the amount of time an INVITE transaction remains active after completion with a 2xx response to handle response retransmissions. |
TU2 |
Sets the amount of time the server waits for a provisional or final response for an INVITE client transaction or NONINVITE server transaction after which the transaction is considered timed out. |
clientTn |
Sets the maximum lifetime of a client transaction. |
serverTn |
Sets the maximum lifetime of a server transaction. |
Provisional (TU3) |
(Optional) Configures SIP networks with TU3 transmission type only. |
INVITE Client Transaction |
Specifies the retransmit count for the INVITE request. |
INVITE Server Transaction |
Specifies the retransmit counts for final responses of INVITE requests. |
Client Transaction |
Specifies the retransmit count for requests other than INVITE. |
Step 4 Update the values.

Viewing and Deleting SIP Listen Points
A SIP listen point, or listener, listens for SIP traffic on a specific SIP network, host, and port. You can configure multiple SIP listen points for a single network; however, you must create at least one before the server can accept SIP traffic.
Note ● You do not have to disable listeners on the network when you make configuration changes to the network.
- You cannot run TCP and TLS listeners on the same port.
Procedure
Step 1 Choose Configure > Networks.
The system displays the Networks page, listing all of the current networks.
Step 2 To see the SIP listen points associated with a network, under the SIP Listen Points header, click click here.
The system displays the Network ‘<name of the network>’ page with the SIP Listen Points tab highlighted.
Note To see a different number of SIP listen points on each page, on the top right, choose another number from the drop-down box and click Go. You can choose to see 10, 25, 50, 100, or all SIP listen points. To move to another page, use the left and right arrow buttons on the bottom right, or enter another page number and press Enter.
Step 3 To delete a SIP listen point, do the following:
a. Check the check box next to the name of the SIP listen point.
b. Click Remove.
