При звонке , трубка снимаеться, слышу "хеллоуворд" и сразу обрыв или "хандап" толи из-за редалармов толи в плане ошибка, хотя план делал по книжке.

Посмотрел в гугле , вроде как Red Alarm идет из-за телефонного провода, провод проверил- все нормально.
хелп!

надо понимать у тебя телефонная линия (из города) воткнута в порт карты?
Начинать надо не с "хеллоуворд", а с команд
ATC#dmesg
ATC#cat /proc/interrupts

безо всякого Астериска.

да, телефонная линия из города

вроде все нормально

ходил к "соседу", подключался к его линии...теже алармы и сброс..((

включил дебаг, оставил по дефолту 3 и в консоли увидел какую-то фигню..

разбираюсь дальше,может и выйдет каменный цветок)

Установи для приличия
loadzone = ru
defaultzone = ru
и померяй напряжометром вольтаж в линии: в состоянии покоя (hang off), во время звонка и при поднятой трубке (hang on).
найди в библиотеке asteriskforum.ru документ о стандартах в российиских сетях связи.
