Enterprise Session Border Controller (E-SBC)

Navigate to "VoIP">"SIP" to configure the SIP server info for Lineblocs. Enter in the SIP Server FQDN assigned for these services under the SIP Server Address field. Fill in the SIP Server Domain field with the proper Lineblocs domain.

Note: Make sure to check the "Limit Inbound to listed Proxies" and "Limit Outbound to listed Proxies" boxes to help prevent fraudulent activity sourced from a LAN side PBX or a WAN side DoS attack.

Navigate to "VoIP ALG" and then "B2BUA" to configure the SIP Trunk registration with the soft-switch (between the Ribbon EdgeMarc and the WAN side soft-switch), the PBX for SIP registration mode (between the PBX and LAN side of the Ribbon EdgeMarc), inbound rule (for sending SIP messages from the WAN side of the Ribbon EdgeMarc to the PBX) and outbound rule (for sending the SIP messages from the Ribbon EdgeMarc to the WAN soft-switch). RFC-4904 support will be handled by applying header manipulation action rules to the matched outbound rules.

Configuring the PBX for SIP registration mode (between PBX and the Ribbon EdgeMarc). From the "Trunking Devices" section:

Click the "New Row" button to get to a new entry for a Trunking Device.

Select IP Registration mode by selecting the radio button for using the IP field and Port field.
Enter the PBX IP in the "IP" field.
Enter 5060 in the "Port" field. Click "Update" to create a Trunking Device for PBX. Click "Submit" at the bottom of the page to send the config to the Ribbon EdgeMarc.

From the Actions section:

Click the "New Row" button to get a new entry for creating an inbound action.
Enter the action name in the "Name" field.
Select the radio button of "Trunking Device".

Select "InboundAction" from the drop-down list of the "Action" field.
Click the "Update" button.

From the Match section:

Click the "New Row" button to start a new entry for an outbound rule.
Select "Outbound" in the "Direction" field.
Select the radio button of "Pattern match", select "Calling" from the drop-down list, and enter a "." or match the partial DID map (for example, if there is 6785551111-1115, then use 678555111X) in the "Pattern match" field to match any calling numbers.
Select "Any" from the "Source" field.
