I just attempted to upgrade my 1.4.1 box to 1.4.2. I deleted all of the existing modules under /var/lib/asterisk/modules, then recompiled zapata-1.4.0 and libpri-1.4.0. After running configure and make menuselect, I discovered that the chan_zap channel was XXX’ed out under Channel Drivers.
Assuming a dumb ass attack on my part, I recompiled everything a second time and had the same results.
I went back to asterisk-1.4.1 and after running configure and make menuselect chan_zap was available.
I have a TDM400 card installed, so zaptel is not optional. Anyone else experiencing a similar problem?
