Полная перезагрузка Asterisk решает проблему - но не надолго ( пару часов проблемы нет). На Выходных когда звонков нет , соот нет и ошибок

А zttest что говорит?
Вообще интересно, а алармов при этом же не наблюдается в логах/zap show status?
Если включить pri intense debug, что в эти моменты происходит?

проверьте, должен ли присутствовать crc

Что изменилось со среды на Вашей стороне?

В том то и дела , что ничего не меняли

Хорошо бы поглядеть на логи несколько экранов до падения д-канала т.к. d-канал убивается только после 3х пропущенных ack'ов на фреймы (t200 timer)

Кстати, а на той стороне что видно в момент падения d-канала? сам поток падает, есть алармы?

На другой стороне все чисто никаких алармов нет

Тут нет никаких ошибок, видимо оно случилось пораньше, надо логов больше, еще минут за 5.
Лучше все-таки портянки куда-нибудь в радиус paste.org.ru выкладывать

И все же - что происходит с другой стороны в момент X? Разумно было бы пообщаться с аплинком и получить от них какую-то диагностическую информацию, если они не сознАются что у них чего-то там поменялось.
Кстати, звонки, отлетающие массово по reason 31 normal, unspecified настораживают.
У меня такое было один раз в одном сетапе, аплинк обьяснял что видит проблемы с синхронизацией из-за плохого канала

Я думаю нада провайдера покрепче за яйцы взять. Пусть колется что там у себя поменял. я пару раз с таким сталкивался.

Свич, чё-т последнее время грубияном стал! А если сисадминша читать пост будет? Неудобно ж будет!
