Summary:                    ReceiveFax doesn't work with attended transfer
Description: 
SIP/208 (Panasonic-Fax in Linksys SPA2102) calls SIP/115 (Linksys SPA504G)
with app_dial. SIP/115 answers and presses Xfer-button then dials 158.
After i hear CNG from ReceiveFax, i press Xfer on SPA504G again to complete
transfer. After that SIP/208 and ReceiveFax are connected, but i don't hear
CNG in Panasonic-Fax, so fax transmission from SIP/208 to ReceiveFax fails.

[fax]
exten => s,1,Answer()
exten =>
s,n,Set(FAXFILE=/mnt/fax_kw12/fax_${STRFTIME(${EPOCH},,%Y-%m-%d_%H-%M-%S)}.tif)
exten => s,n,ReceiveFax(${FAXFILE})
exten => h,1,System(chmod 777 ${FAXFILE})
exten => h,n,NoOp(${FAXSTATUS})
exten => h,n,NoOp(${FAXERROR})

[office1]
exten => _XXX,1,Dial(SIP/${EXTEN},,tT)
exten => 158,1,Goto(fax,s,1)

This scheme doesn't work only with Attended Transfer and works fine with
Blind.

I've uploaded sip-debug on this call.
Imadsen, may be you are true, but it is rather difficult for users to do
both blind and attended transfers. I think faxdetect works only on
SIP-2-SIP calls and i've got H.323 lines too.
