This guide for setting up easybell Business SIP Trunks in Panasonic IP phone systems of the KX-NS series also includes the settings required for inbound DDI routing and outbound CLI presentation.

Please note that the configuration screens of newer versions may differ from those shown here.

In order to use all functions as described here, you require an easybell Business VOICE connection. Please make sure, you’ve read our information about the format of phone numbers for incoming calls.

 

1. SIP Trunk Provisioning

1.1 Port Properties

If several SIP trunks of different providers are used, it is recommended to use a separate gateway for easybell. In the Panasonic web interface, go to "1.1 Slot" under "PBX configuration" and open the port properties for the virtual gateway card V-SIPGW16 as shown in the following screenshot.

1.1.1 Main Properties

First, a basic channel needs to be defined in the main properties for the virtual SIP gateway. The 3 parameters highlighted in the following screenshots need to be specified. The SIP server port can remain at 5060.

 

1.1.2 Account Properties

In the account properties, the personal access data for the basic channel, which you have received from easybell or that are stored in the easybell customer portal, need to be entered. Username and Authentication ID are the same for easybell.

 

1.1.3 Register Properties

The registration details for the trunk are as follows.

 

Click on "OK" to save your configuration.

 

2. Outgoing Caller ID Presentation (CLIP)

Please note: Currently, easybell functions may not work correctly if, instead of the actual phone number, a CLIP number is to be transmitted, which is not assigned to the easybell customer account. Affected easybell features include timed voicemail and conference calls. Therefore, please set these functions directly in the telephone system.

2.1 Calling Party

In order to have the correct caller ID (CLIP) displayed to the called party, the header parameters under "Calling Party" should be adjusted as shown below.

 

2.2 Supplementary Service

As CNAP / CNIP is not supported by easybell, the feature should be disabled in the Supplementary Services tab of the Port Properties. It is also recommended to evaluate the received CLIP from the From header.

 

Click on "OK" to save your configuration.

 

3. Calling Line Identification Presentation (CLIP)

In the Panasonic web interface, go to the "Extension" settings under 4.1.1 and open the "CLIP" tab. Enter the desired "CLIP ID" for each extension in the required format. Take into account the input entered as part of section 2.1 "Calling Party" regarding the phone number format.

 

3.1 Calling Line Identification Restriction (CLIR)

For anonymous calls, go to the "CLIP" tab from the previous section and activate the CLIR function.

 

Click on "OK" to save your configuration.

 

4. DDI/DID Routing Table

In the Panasonic web interface, go to "Office & Call Distribution" and "10.3 DDI / DID Distribution (DDI)" to assign extensions to phone numbers. The specification of a DDI / DID name is optional and only for your reference.

 

5. NAT Settings and Port Forwarding

To avoid problems behind NAT devices, the Keep-Alive function should be activated. In the Panasonic web interface, go to the "1.1 Slot" settings under "PBX configuration". Move the mouse pointer over the gateway card V-SIPGW16 and temporarily change the status of the card to "OUS" (out of service).

Then, open the "shelf properties" as shown in the following figure as indicated below.

 

If the Keep Alive message from easybell (e.g. OPTIONS / BLANK UDP packets) is not used to maintain port forwarding for an external router, enable BLANK UDP for the Keep Alive message as shown in the following figure. "NAT - Keep Alive Packet Sending Interval" should be shorter than the port forwarding expiration time of the router.

 

Click on "OK" to save your configuration.

If you do not proceed with the next paragraph, go back to the "1.1 Slot" menu. Move the mouse pointer over the gateway card "V-SIPGW16" and reset the status of the card to "INS" (in-service).

To protect the PBX from cyber attacks, restrict the above port forwarding to be only accessible from the IP addresses of the easybell source.

 

6. Deactivating 100rel / PRACK

Although easybell supports the 100rel / PRACK function, it does not exactly match RFC3262. Therefore, problems with additional functions such as call diversion 302 may occur.

To deactivate the 100rel / PRACK function, go to the "1.1 Slot" settings in the Panasonic web interface under "PBX configuration". Move the mouse pointer over the gateway card V-SIPGW16 and temporarily change the status of the card to "OUS" (out of service).

Then, open the "shelf properties" in "1.1 Slots" and deactivate the 100rel / PRACK function in the "main menu".

 

Click on "OK" to confirm your configuration. Then, go back to the menu "1.1 Slot". Move the mouse pointer over the gateway card V-SIPGW16 and reset the status of the card to "INS" (in-service).
