ОХЕ R9.1 (i1.605.37.a) кристалл

к SIP-транку подключен SAP BCM (Call-Center)
соединение с провом через PRI

проблема заключается в следующем - при звонках в PSTN с терминала SAP_BCM не передается dtmf тобишь если позвонил на дису но жми не жми клавишу цифр dtmf через pri не идет акустически

на терминале SAP_BCM в плане dtmf очень скудно, т.е. имеется только rfc2833 (что и включено)

в ОХЕ на ext-gateway который идет на SAP_BCM включена опция "INFO metod remote ext"

ниже лог где с терминала нажали цифру "1"
