Installing and Configuring a Sangoma Card on ScopTEL PBX

ScopServ Integration

Full integration and support for Sangoma cards is included in ScopTEL PBX and includes a quick and easy way to configure all Sangoma cards directly from the ScopTEL PBX Web management interface.


Sangoma Digital/Analog Cards

Sangoma makes a series of PCI and PCI Express cards that can be installed in any server and allow the user to use a PRI line, a T1/E1/J1 line, regular telephone lines (connected to FXO Ports), or to connect standard analog phones (connected to FXS Ports). A PRI Line and T1/E1/J1 line are Digital lines that are usually supplied by either a local telephone company or a provider of business telephone and data services. The most common Sangoma cards used in ScopTEL PBX installations are the A100 (Digital), A200/A400 (Analog),  and A500 (ISDN) series.


Supported Cards

The following cards are supported by ScopTEL PBX :

Analog (FXO/FXS)

Digital (T1/E1/J1)


Hybrid (Analog + Digital + BRI)


ScopTEL PBX users do not need to install Wanpipe (Sangoma) drivers because the latest version of all Wanpipe kernel modules and Wanpipe tools are automatically installed with every installation. We always provide latest Wanpipe version on ScopServ RPM repository.

  • Install one or more Sangoma cards on the server
  • Enable Digital and/or Analog interfaces on Telephony -> Configuration -> Telephony Modules (see image below)

How to fix DAHDI/WANPIPE drivers issues on ScopTEL PBX

If you have updated your ScopTEL PBX server  to use a new CentOS kernel, it can sometimes happen that DAHDI/WANPIPE drivers need to be recompiled manually.

If you’ve been getting issues with Digital/Analog interfaces and drivers refuse to start, here’s how to fix it.

To fix the problem, we’ll need to remove current installed drivers. So open an SSH connection to the server and execute the following commands:

service asterisk stop

service dahdi stop

rpm -e dahdi wanpipe dkms-dahdi dkms-wanpipe  –nodeps

Now that drivers are cleaned, you must reinstall drivers, this step will always download the latest version available on ScopServ RPM repositories.

You must execute this command from SSH to reinstall packages:

scopserv_yum install dkms-dahdi dkms-wanpipe -y

Finally, from the ScopTEL GUI, you must Commit configuration on the Telephony module.

Then it is recommended in SSH to do:

service dahdi start

service asterisk start

As you can see, the procedure for reinstalling  the DAHDI and Wanpipe drivers on your ScopTEL PBX is relatively simple.
