Hello Ryan, I have. There was a discussion on this list a short while ago on howto debug frameslips. I think you could find useful information in that thread. I had the same problems using hfc cards with bristuff. (with patched zaptel drivers). When I applied Florian Zumbiehls patch the problem went away. (The link to the patch can be found in the wiki: asterisk zaphfc) Is it a possibility that there is a problem with interrupt handling in the zaptel driver for other cards as well? /Nils > If that's the case, then my secondary approach is going to have to be: > PSTN <-> Asterisk + chan_h323 <-> t38modem + Hylafax > > Is there anybody that could help me with either of these solutions? > > A thousand "thank you"s in advance, > > Ryan VanMiddlesworth > > > On Thursday, January 6th, I wrote: > > I've been pulling my hair out trying to get Asterisk to receive and > > decode a fax using spandsp and app_rxfax.
