UK DAHDI Multi Line Hangup Detection Problem

Hi all. I’m struggling with hangup detection on FreePBX / Asterisk 13.7.2 / DAHDI Version: 2.11.0 / 4 port TDM410P on a 4 lines with the same number setup.

I’ve followed details here and it seems I need to add “options wctdm opermode=UK fwringdetect=1 battthresh=4” somewhere. The problem is, where do I put this? I can see /etc/modprobe.d/dahdi.conf but being FreePBX rather than standalone Asterisk, I know that straightforward config file modification isn’t going to help me.


With very few exceptions DAHDI is straight Asterisk all the time. Set up your files the way you want them and don’t let FreePBX update them. You should be good to go.
