сама связь есть, атс панасних 600, была 500 и раньше нормально аботала, вроде когда меняи то настройки перенесли, но где это посмотреть знаю смутно,   проблема в том что во время разговора по тунелю появляется шипение или обрыв свази а потом либо связь снова появляется либо приходится перезванивать, есть тунель до провайдера через интернет,  голос берется с тунеля и кидается в е1 на циске, а потом в атс, настраивал не я =( поэтому и копаюсь
