I don’t know what you mean by the stop references. If you mean the call
fails, then that could be because the call attempted to use a channel
not provisioned for your PRI line. Your configuration provisions all
30 channels for an E1 line when you said you have 20 channels.

^^^ This line is creating all of the channels for an E1 so chan_dahdi
thinks it has all 30 channels available. You said you only have 20
channels available so the channels line is wrong here. It should be
something like
channel => 1-15,17-21

Also anything after a channel line does not apply to the channels created
by a channel line.

^^^ This channel line is wrong. It attempts to redefine channels
you have already defined earlier by the dahdi-channels.conf include.
You should have gotten warning messages when Asterisk loaded about
channels already defined.
