  1. Fist after installing RasPBX make sure to run raspbx-upgrade in putty to update everything.
  2. Next type 'nano /etc/asterisk/alsa.conf' and modify it to look like this.

input_device=hw:1,0
output_device=hw:0,0

  1. Then type 'nano /etc/asterisk/modules.conf' find 'noload => chan_alsa.so' and change it to 'load => chan_alsa.so'
  2. Reboot the RPi for the changes to take effect.
  3. To adjust the volume issue 'alsamixer' in putty and adjust accordingly.
  4. Go into extensions in FreePBX and create an 'Other (Custom) Extension'. In the dial parameter input 'console/alsa'.

NOTE: If the HDMI cable is plugged in it will take precedence over the analog output. Make sure the HDMI isn't hooked up when the RPi starts up to use the analog line.
