ded, эта скорлупа на данный момент не по моим зубам.
нужно срочно. по-сему готов оплатить.

Значит можно без AGI -
exten => s,n,NoOp(HANGUPCAUSE is ${HANGUPCAUSE})
exten => s,n,gotoif,($[${HANGUPCAUSE} = 28]?s-INVALID,1)
exten => s-INVALID,1,Playback(invalid)

Правда это надо вставлять в macro-dialout-trunk-predial-hook, потому что macro-dialout-trunk - динамический, находится в extensions_additional.conf и перепишется при первом Apply.

попробовал дедовский способ. вставил в макро приведенные строки, сохранил. перечитал конфиги - без изменений.

пишите на ICQ 173874210

Вчера я уже пообщался по ICQ, самым разумным я вижу произносить сообщение через AGI и опцию фрисвитча Monitor Trunk Failures

) имхо есть другие варианты, поскольку сип еще ложит в какуюто переменную именно сип резултат(сделайте дамп).

вариант от IgorG со скриптом работает. довольно просто и эффективно. понаблюдаю еще за работой и отпишусь
