> Приветствую. У Вас какое-то редкое колдунство. это точно!!!
>Покажите весь маршрут - pri-mgcp-ucm и дальше как и куда, на ip телефон?
порт провайдера --- модем какойто разер (меняли на другой) --- pri --- 2811 филиал тут варианты (1,2 описаны ниже) --- mgcp --- CUCM (кластер)
варианты:
1. FXS - подключены факсы (на входящих факсах периодически возникают пролемы)
2. порт в голосовой влан на ip телефоны - подключены через cat2960 на телефонах при входящих! с PRI есть проблемы.
>Вы уверены что дело не в потерях, будь они на IP сети
да, т.к. даже факсы на этом гейте глючат исключительно на входящие.
>или SLIP'ы на потоке?

все параметры проверили с провайдером, есть некое подозрение на "Echo Cancellation" включено с двух сторон (вопрос проверяется).
