t38 gateway

Question

Необходимо, чтобы заработал t38 gateway в Asterisk. Использую Asterisk 1.8.10 вот с этим патчем https://issues.asterisk.org/view.php?id=13405.

Схема включения:

FAX1 <> FXS <> ASTERISK1 <> IP <> ASTERISK2 <> FXS <> FAX2

Между двумя астерисками sip trunk. Настройки факса в sip.conf

t38pt_udptl = yes,redundancy(пробовал все возможные).

Экстеншн на входящие:

[fax]
exten => 118,1,NoOp()
exten => 118,n,Set(FAXOPT(gateway)=yes)
exten => 118,n,Dial(SLIC//dev/si3226x_fxs1.0,600)

Экстеншн на исходящие:

[fxs1]
exten => _7.,1,NoOp()
exten => _7.,n,Set(FAXOPT(gateway)=yes)
exten => _7.,n,Dial(SIP/trunk_2/${EXTEN:1}, 30)

Астериски с двух сторон настраиваю симметрично.

Вот часть вывода asterisk -rd:
