HI Troy,

There are frame slips in your audio stream. That is why things go wrong. The QAM modulation used for most of the faster modems (including the FAX modems) cannot tolerate even a single audio sample dropped from the stream - it represents a huge phase shift :-\

Are you using a T1 oe E1? If so, check your clock source. The commonest reason for sample slips is that you are not synching to the network.

Regards,
Steve

Running spandsp 0.0.1k, tiff 3.5.7.

I put some audio log files in the same directory.

Thanks,

Hi Troy,

People had a lot of problems like this with earlier versions of spandsp. However, the latest version is pretty solid, and people are using it in high volume production applications. If you are getting these bad results with the latest version I would be interested to see the audio log file, so I can investigate the reason.

Regards,
Steve
