Sangoma-NetBorder Configuration

Using this topic, you will achieve the following installation and configuration:

  1. Install the Sangoma A108E card into your server.

  2. Do not install the card drivers, as NetBorder Express has it's own drivers.

  3. Install and configure Windows 7 64bit.

    Make sure networking is properly configured before proceeding.

  4. Download NetBorder Express
  5. Run NetBorder Express installation and follow the prompts.

At the end of installation, you will be presented with a web-based Gateway Manager interface. The Quick Setup Wizard will help you set up a new system configuration.

  1. Hardware configuration - select your Sangoma board (B1 - A108_digital) and make sure only one interface is selected
  2. Choose your country
  3. PSTN digital configuration. - choose interface type E1, signaling type CCS (PRI ISDN), framing CRC4, encoding HDB3 and ISDN switch variant NET5
  4. SIP configuration - define on which ports NetBorder Express will listen for UDP and TCP connections. The default port is 5066. Choose primary listening IP address 10.0.0.193
  5. Call routing configuration - SIP transport UDP. Primary SIP server address will be STG address 10.0.0.88 and port 5060
  6. Services configuration - select automatic start and restart on failure

After the wizard finishes do not start/ restart the gateway. Instead,

  1. select the Configuration tab
  2. select the PSTN Config tab
  3. tune your card configuration

If you are installing the free version of NetBorder Express, the gateway will not start if you have too many channels configured. The free version only allows 12 channels.

Click on Assigned BChannels and configure as below.

  • Board ID: 1
  • Interface ID: 1
  • First channel: 1
  • Last channel: 12
  • Channel group ID: default

Save the configuration and start the gateway. To start:

  1. select Status and Controls tab
  2. select Controls tab
  3. click Start Gateway

If it does not start, select File Browser tab, expand logs and inspect the log files for errors.

Net Border Express does not set ToS byte by default. In Advanced Configuration, set netborder.media.rtp.tos to 184.

On all STG hosts, check that the following Windows registry setting is correctly configured:

From V10.6.390 - this setting is now configured by default.

  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  • Setting: DisableUserTOSSetting
  • Type: REG_DWORD
  • Value: 0

STG must translate agent extensions to their softphones and everything else to the NetBorder Express gateway:

<addressTranslations>
  <translate address="7" translated="sip:7@10.1.0.10:65000" />
  <translate address"*" translated="sip:*@10.0.0.193" />
