Hi guys, I found solution, but I can't tell exactly what it was. I installed on clean Debian system asterisk 1.4.19 and newest zaptel, libpri, and stuff from sip.fontventa.com and it finally worked. I can't tell you if it was fault of some outdated libraries (system on which I installed previously was highly used for various development things), or maybe fault of using dahdi package. So anyway, it worked, thanks for all helpful info. Regards,
