So last night thanks to the help of the fine folks on this list I got the newest Zap 1.4 and Asterisk 1.4 compiled and installed and seemingly working except that after a few calls and a few keystrokes I get a kernel panic. The first time I had just typed reload after cleaning up some deprecated commands, the second time I had just pressed Alt+2 to get to another session. So 1.2 is back and working as it always has. This is the same problem I had when I installed the first version of 1.4 so there is clearly something wrong with 1.4 or my computer or install. Any and all suggestions welcome. I'd rather not reinstall Linux, but if it's the only choice, I will. It's CentOS with yum update run recently and all updates applied. It was originally installed from a TrixBox disk about 2 years ago so I guess it's CentOS 4. Ira
