Fax+asterisk не работает прием нескольких страниц

Есть Астер 11, факс настроен через spandsp, протокол t38 Прием факса Код:

exten => 2193,1,Answer 
exten => 2193,2,Ringing() 
exten => 2193,3,NoOp(incoming callerid ${CALLERID(num)}) 
exten => 2193,4,Set(FAXOPT(ecm)=yes) 
exten => 2193,5,Set(FAXOPT(headerinfo)=MY FAXBACK RX) 
exten => 2193,6,Set(FAXOPT(localstationid)=My) 
exten => 2193,7,Set(FAXOPT(maxrate)=14400) 
exten => 2193,8,Set(FAXOPT(minrate)=4800) 
exten => 2193,9,Set(tempfax=${STRFTIME(,,%C%y%m%d%H%M)})

exten => 2193,11,System(/usr/bin/tiff2pdf /var/spool/asterisk/fax/${tempfax}.tiff -o /var/spool/asterisk/fax/${tempfax}.pdf) 
exten => 2193,12,System(echo "Принят факс" | mailx -s "fax" -a /var/spool/asterisk/fax/${tempfax}.pdf dyuryagin.ms@transasia.ru) 
exten => 2193,13,Wait(1) 
exten => 2193,14,Goto(internal,2198,1)

Первую страницу принимает нормально, а вот после перевода обратно на оператора, последующие страницы не принемаются, хотя в логах вроде прием идет, может можно как-то по другому реализовать прием нескольких страниц?
