[Asterisk-Users] scandsp, voicetronix and rxfx
Hi all,
Trying to get fax reception going using a voicetronix openline4 card,
however, there are two issues (as far as I can see)
(1) Currently the voicetronix world (cards, firmware, drivers, channel
prog etc.) does not do fax tone detection. I have spoken to the
voicetronix guys , understand what has to happen there and may do some
hacking if I can resolve the second issue. Meanwhile, I guess I can do
some sort of manual (or pseudo manual) transfer to a spandsp extension.
(2) More worringly, when I do force a transfer to rxfax, it does not
appear to train with the fax machine that I am using (samsung sf-330).
Here is a snippet of log:

and this repeats ad nauseum until the fax machine gives up.
Any ideas what the issue might be anyone? Could this be voicetronix
card-related?
Thanks in advance.

FYI, I've been having the exact same problem with a certain fax machine (in my case a software based one). I've tried the latest from opencall.org v1-0_STABLE and the latest CVS-HEAD. Faxing is definitely tricky work - and I imagine there are hundreds of variables that could cause it to fail. On a positive note - it does appear to work with _some_ fax machines. Can anyone out there offer some tips regarding getting rxfax to work better (aside from links off of wiki)? Like maybe playing a background sound before executing rxfax or something crazy like that?> > -- Executing SetVar("vpb/1-1", "FAXFILE=/tmp/1086048253.8.tif") in > new > stack > -- Executing RxFAX("vpb/1-1", "/tmp/1086048253.8.tif") in new stack > Changed from phase 0 to 1 > Slow carrier up > Slow carrier down > Slow carrier up > Slow carrier down > Slow carrier up > Slow carrier down > Slow carrier up > Slow carrier down > Start receiving document > Changed from phase 1 to 4 > Sending ident >>>> CSI: 40 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 > DIS: > Preferred octets: 256 > Can receive fax > Supported data signalling rates: V.27ter and V.29 > R8x7.7lines/mm and/or 200x200pels/25.4mm OK > 2D coding OK > Scan line length: 215mm > Recording length: A4 (297mm) > Receiver's minimum scan line time: 0ms at 3.85 l/mm: T7.7 = T3.85 > R8x15.4lines/mm OK > Minimum scan line time for higher resolutions: T15.4 = T7.7 >>>> DIS: 80 00 ce f0 80 80 01 > HDLC underflow in state 9 > Changed from phase 4 to 3 > T4 timeout in state 9 > Changed from phase 3 to 4 > Sending ident >>>> CSI: 40 08 13 7c 58 f0 7a 15 af 14 c6 ef 10 e7 61 0b 44 1b 20 fb 59 > DIS: > Preferred octets: 256 > Can receive fax > Supported data signalling rates: V.27ter and V.29 > R8x7.7lines/mm and/or 200x200pels/25.4mm OK > 2D coding OK > Scan line length: 215mm > Recording length: A4 (297mm) > Receiver's minimum scan line time: 0ms at 3.85 l/mm: T7.7 = T3.85 > R8x15.4lines/mm OK > Minimum scan line time for higher resolutions: T15.4 = T7.7 >>>> DIS: 80 00 ce f0 80 80 01 > T2 timeout > Start receiving document > ... > > and this repeats ad nauseum until the fax machine gives up. > > Any ideas what the issue might be anyone?
