Zttest: no results

Hi!

I have a problem concerning zttest (and therefore running asterisk):
After installing asterisk by a fried of mine, it didn’t really work. Compilation and installation were successfull, but testing the ISDN-interfaces via zttest failed; running zttest leads to no results, there is a loss of 100%.

lspci:
