You might try using spandsp-0.0.6-pre17. That version works great for me with 1.8.4-rc2. When I tried pre18 it failed to receive any faxes. Of course, such an important regression was duly reported to the author, wasn't it. Steve I wasn't sure if it was my problem or a regression with the release. When I had searched nobody else mentioned the issue. I'd guess I have around a 70% success rate with pre17 over ulaw from free fax services. When I briefly tested pre18 I couldn't get any to come through. I do appreciate your effort with spandsp. 70% is awful. You should be getting 99%, unless this is VoIP over a sucky network.

I can't help with this. faxbuffers=6,full ; who knows what this does But I do know that this faxbuffers policy basically is telling the kernel to allow ~120ms of audio to build up before shipping it out to the physical board. This is to work around problems where scheduling jitter on the host computer would prevent the asterisk process from keeping the DAHDI channel full and fax machines do not handle gaps in the audio very well. This is more pertinent if you're connecting a real fax machine to an FXS port.
