Configure DAHDI for FreePBX on Appliance with FXO/FXS ports

• After you have downloaded and installed FreePBX ISO or another FreePBX based system from https://www.freepbx.org/downloads/ you will need to download and install our patched version of DAHDI for the 716, 716 or 745 Appliances.

715, 716 and 745

• Log into your PBX with SSH

• We need to make sure we have the kernel-headers and kernel-devel packages installed

  • yum -y install kernel-headers kernel-devel

• Reboot the PBX now

• Download the DAHDI src here

  • dahdi-linux-complete-2-1…

• Extract the file to /usr/src

  • tar zxvf dahdi-linux-complete-2-11-1-2-11-1-SGM-20191120-tar.gz -C /usr/src/

• Change to the directory we just extracted the file to

  • cd /usr/src/dahdi-linux-complete-2.11.1+2.11.1/

• Build and Make DAHDi

  • make

    • Note: If after running the make command, you get an error message like: "You do not appear to have the sources for the 3.10.0-xxx.xx.x.el7.x86_64 kernel installed."

  • 

    • Then you may be missing a symlink to the sources location.
      The command below should resolve that. Rerun the commands above once the symlink is fixed.

      • ln -s /usr/src/kernels/$(uname -r)/ /lib/modules/$(uname -r)/build

  • make install

  • make config

• Reboot the PBX now

Prevent Dahdi Drivers from being overwritten by system updates.

• Add "exclude=dahdi-linux* dahdi-firmware* dahdi-tools* kmod-dahdi* asterisk*-dahdi wanpipe* kmod-wanpipe*" to the yum config

• echo "exclude=dahdi-linux* dahdi-firmware* dahdi-tools* kmod-dahdi* asterisk*-dahdi wanpipe* kmod-wanpipe*" >> /etc/yum.conf

Additional Steps of 715 and 716 only

• The 715 and 716 need the following scripts to handle updating the LED lights on the appliance for the FXS and FXO ports.

• log into your PBX with SSH and wget the following script

• dahdisetup.sh

• make the file executable

• chmod +x dahdisetup.sh

• run the script

• ./dahdisetup.sh

• If you get an error on the dashboard

  • "Unable to write to /etc/wanpipe/global.conf"

  • You will need to run the following 3 commands to fix it.

    • mkdir /etc/wanpipe

    • touch /etc/wanpipe/global.conf

    • chmod 777 /etc/wanpipe/global.conf
