In case it helps others, a couple gotchas that I had to dig and beat my head against to get past... - building on FC2, use "make linux26" when building asterisk - also for FC2, a couple links in /usr/src named linux and linux-2.6 and pointing to /lib/modules/2.6.8-1.521/build/ were needed to build - yes, the power connector on the TDM400P needs to be connected to the power supply - modify the zaptel init script to use modprobe instead on insmod That last one killed me ;) Paul -- Paul A.
