End of Life Products and Features - Configuring Netborder Express Gateway for Express for Lync 2.0
Overview
Your Express for Lync appliance comes with an embedded VoIP gateway call Netborder Express. This gateway can be used to integrate Microsoft Lync enterprise voice services with the Public Switched Telephone Network (PSTN). If you are using a Sangoma Digital T1/E1 board, you must speak with your telecom provider to see what settings you would require for the following requirements:
Interface Type (E1, T1, J1)
Framing Type (ESF,D4, NCRC4, CRC4)
Encoding Type(B8ZS, AMI, HDB3)
ISDN Switch Variant (4ESS, DMS, NI2, NET5, MFC/R2)
Once the information above has been found, you can start the configuration of Netborder Express.
Configure Netborder Express Gateway
In order to configure Netborder Express, please use the instructions below:
Launch the Netborder Gateway Manager from the windows desktop link labelled "Gateway Manager".
This will bring you to the Netborder Express Gateway web based user interface : the Netborder Express Gateway Manager. Select the "Quick Setup" tab as highlighted in the following image.
Once in the quick setup page, click the "Next" button to continue.
This screen will display the available telephony (A-Series) boards in the system. For this guide, we have an A200 and an A108 installed.
Any A200 with FXS modules should be configured like the matrix below:
Interface ID | Caller Name | Phone Number |
1 | FXS1 | 1001 |
2 | FXS2 | 1002 |
3 | FXS3 | 1003 |
4 | FXS4 | 1004 |
For any digital boards (A108), you should just select the number of ports you would like configured. Once all configuration options have been selected, click "Next" to continue.
Select the country in which the Express for Lync appliance is being deployed from the dropdown selection. Click "Next" to proceed.
In the PSTN digital configuration screen (see image below), select the settings corresponding to your telecommunication service provider. For this guide, we have chosen to use "T1" settings. When done, click the "Next" button to continue.
The next screen allows to make you to make adjustments on audio parameters coming from the PSTN network. For example if the audio level coming in is too loud or too weak, gain adjustments can be done here. For the initial configuration, we can leave this configuration disabled. Click the "Next" button to continue.
Here you can change the SIP related configuration. This configures the link between the Lync mediation server and Netborder Express. Please make sure that the TCP Port NBE is listening on is port 5081 and the "Primary IP Address" is listed as 127.0.0.1. We suggest that you change the Primary IP Address to the physical IP address of the INTERNAL Interface as leaving it at 127.0.0.1 can cause issues. Click the "Next" button to continue.
9. This screen defines where to send incoming and outgoing calls.Make sure that the "SIP Transport for outgoing calls" is set to TCP and the "Primary SIP Server Port" is port 5068. Click "Next" to continue.
This screen defines the NetBorder Express service properties at Windows startup and in case of failure, we suggest you keep the defaults value and click "Save" to continue.
On the final screen, you will notice on the bottom right corner that the status indicates that the configuration is out of sync (as highlighted in the image below). This means that the configuration has changed and the gateway needs to be restarted in order to apply the modifications. To do so, click on the "Restart Gateway" button.
When the restart process is completed, the screen shown below will appear.
Configure Lync Server to use Netborder Express as a PSTN Gateway
If you are configuring Lync Server to only use Netborder Express as a PSTN gateway, then you would need to add it into the Lync Topology. To do this, you must follow the steps below:
Launch the Lync Server Topology Bulder from the windows desktop.
When the topology builder launches, select "Open Topology from a local file" and click "OK".
Select your topology from the "Open" window and click "open".
When the topology builder loads the topology, navigate down to Trunks by going through Lync Server -> Topology -> Shared Components -> PSTN gateways. Right click on PSTN Gateway and select "New IP/PSTN Gateway...".
In the "Define New IP/PSTN Gateway" wizard, enter the FQDN or the IP address of the Netborder Express. The IP address should be the same IP Address of the Express for Lync appliance.
In the next window, leave everything at defaults and click "Next".
In the next screen, you will be asked to define the root trunk. In the listening port of the IP/PSTN gateway, enter port 5081. Under SIP Transport Protocol, select "TCP". Everything else can be left at defaults. Click "Finish" to end the wizard.
When returned to the topology builder, will you notice the PSTN gateway has now been populated.
We now need to publish this change in the topology so that Lync Server can use the gateway. Right click on the root "Lync Server" and select "Publish Topology".
When the Publish Topology wizard opens, click Next to proceed.
The wizard will then ask you to select the server which will host the Central Management Store. Select the Express for Lync appliance from the dropdown list and click Next to proceed.
The Publish Topology wizard will now publish the topology to the SQL store. This may take several minutes. Once completed click "Finish" to close the wizard. You can then close the Topology builder.
