Requested DTMF feature disconnect not available

Getting this error when dialing out:
[May 1 15:10:48] ERROR[151341][C-0000003d]: bridge_basic.c:381 builtin_features_helper: Channel DAHDI/1-1: Requested DTMF feature disconnect not available.

I have this available:

grep discon /etc/asterisk/features.conf

disconnect => *0 ; Disconnect (default is *) – Make sure to set the H and/or h option in the Dial() or Queue() app call!

Im even trying to set it in code like:
FEATUREMAP(disconnect), key

and still get that error.

I guess I should not had moved to 18… not the best experience so far.

I ended up fixing this by removing H but of course now I cant disconnect.

This is probably why

# asterisk -x 'module show' | grep bridge_builtin_features.so
bridge_builtin_features.so     Built in bridging features               0          Not Running          core

don’t understand why it isnt loaded

# ls -la /usr/lib/asterisk/modules/bridge_builtin_features.so
-rwxr-xr-x 1 root root 334104 May  1 12:05 /usr/lib/asterisk/modules/bridge_builtin_features.so

there is always the modules.conf where you can add :

load bridge_builtin_features.so

and see

thanks for the reply… I’m actually already doing that.
