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I can't tell you if it was fault of some outdated libraries (system on which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,

Void.
