Добрый день!
Имеется AddPac AP-IP90 подключенный к Asterisk. При исходящем звонке на занятый номер короткие гудки в трубке не генерируются, на дисплее надпись занято не появляется.
При такой-же ситуации с телефонов AddPac AP-100 и Cisco-502g короткие гудки идут ОК, до того пока абонент не положит трубку.

Как заставить IP90 генерить короткие гудки или хотя бы отображать занято на дисплее?

Конфиг на телефоне:

Проблема решается перепрошивкой AddPac версиями меньшей 8.51 (попробовали v8_50_009 с сайта addpac.com и v8_41_083 с http://www.addpac.su/arhiv.htm).

НО!!! в данных прошивках отсутствуют функциональные кнопки и русский язык меню. Пробуем получить работоспособную прошивку.
