День добрый,
Существует проблема - не проходят факсы в направлении:
cisco 7200 ipipgw (c7200-advipservicesk9-mz.124-20.T.bin) <- gnugk (gnugk-2.2.8, opehn323-1.18.0, pwlib-1.10.3) <- addpac 1000 (проверялись версии 8.30R,8.30T,8.30U)
при том в ОБРАТНОМ направлении передачи факсы проходят.
------------
Адпак не может "понять" PDU t38fax в цепочке (gk->addpac):
gk <- facility (t38fax) H225 TunnH245:on FS:off H245 requestMode
addpac <- (t38fax) H245 requestMode

Q931 PDU UUIE Decode Error
настройки адпака:
voice service voip
fax protocol t38 redundancy 0
fax rate 9600
h323 call start fast
h323 call channel early
h323 call tunnel enable
в случае slow start'а и отсутствия туннелирования факсы в данной схеме ходят.
