Modify an Interface

The Interface Configuration dialog box in Interaction Administrator allows you to modify a SIP interface that defines hardware and protocols that Director uses to communicate with a SIP carrier.

To modify an interface

1. In the tree view, click the Interfaces container. The interfaces display in the Interfaces list view.

2. Right-click the interface and then click Properties. The Interface Configuration dialog box appears.

3. 

3. To change the adapter to inactive, on the Adapter tab, clear the Active check box and the click Apply.

4. To change the protocol settings, do the following:

1. Click the Protocol tab.

Protocol: Name of the carrier. You cannot change this value.

SIP Protocol: Type of SIP protocol.

UDP (User Datagram Protocol): Communications protocol that sends datagram messages from one computer to a program running on another computer. Since UDP is connectionless, the protocol does not guarantee error-free delivery. Programs that use UDP process any errors and check for reliable delivery. This option is best suited for a local network.

TCP (Transmission Control Protocol): Communications protocol that sends a sequenced delivery of bytes to a remote or local user. Since TCP establishes a connection, it is less error prone than UDP, but has greater overhead. This option is best suited when using a WAN.

Address to Use: Network interface for SIP communications.

Domain: SIP protocol domain.

Receive Port: Port that sends and receives SIP messages. The default value is "5060."

Maximum Packet Retry: Maximum number of attempted SIP requests when using UDP as the transport protocol. The default value is "10." This option is an advance UDP setting. Do not change the value except under the direction of PureConnect Customer Care.

Maximum Invite Retry: Maximum number of attempted SIP invite requests that PureConnect Customer Care instructs you to do when using UDP as the transport protocol. The default value is "6." This option is an advance UDP setting. Do not change the value except under the direction of PureConnect Customer Care.

T1 Timer (ms): Initial incremental delay between SIP packet retransmissions when using UDP as the transfer protocol. The default value is "500." This option is an advance UDP setting. Do not change the value except under the direction of PureConnect Customer Care.

T2 Timer (ms): Maximum incremental delay between SIP packet retransmissions, when using UDP as the transfer protocol. The default value is "4000." This option is an advance UDP setting. Do not change the value except under the direction of PureConnect Customer Care.

2. Modify the information and then click Apply.

5. To change the carrier settings, do the following:

1. Click the Carrier - SIP tab.

Carrier: Carrier for the interface. You cannot change this value.

Local Transaction Timeout (ms): Amount of time (in milliseconds) that Director server waits for a routing handler to respond before sending the default response to the carrier. A default response is a valid routing response, but it is not based on the real-time data. Define a default response in Interaction Director for each provisioned number. The default timeout value is 400 milliseconds.

2. Modify the information and then click Apply.

6. To change the carrier numbers, do the following:  

1. Click the Carrier Numbers tab.

2. To add a SIP provisioned phone number, routing action, and default code, do the steps to Add a SIP Provisioned Number.

3. To add multiple SIP carrier numbers, do the steps to Add Multiple SIP Carrier Numbers.

4. To modify a SIP provisioned phone number, routing action, or default code, do the steps to Modify a SIP Provisioned Number.

5. To delete a SIP provisioned number, do the steps to Delete a SIP Provisioned Number.

7. When finished, click OK.
