I am using the following: Asterisk 1.2.17, Asterisk-addons 1.2.5, Asterisk-sounds 1.2.1, and FreePBX 2.2.1.
I had a working Asterisk server but after upgrading FreePBX to 2.2.3, it has the errors shown below. I am not saying upgrading caused it but it may be a factor.
error message from /var/log/asterisk/full:
ERROR chan_zap.c: Signalling requested on channel 1 is FXO Kewlstart but line is in FXO Loopstart signalling
ERROR chan_zap.c: Unable to register channel ‘1’
loadzone = us
defaultzone = us
some portions omitted from this post
channel => 1
Running ztcfg -vvv would result in channel 1-8 as FXO Loopstart and channel 21-24 as FXS Kewlstart.
