Hello, Since our telco messed with our PRI in some way, we get corrupt faxes like these: http://zenon.apartia.fr/stuff/corrupt_fax.pdf We use the lastest asterisk with a TE410P and spandsp. (for some strange reason, our neighbour company has a traditional pbx fed by 7 BRI's and sees the same problem) Now the telco is trying to racket us with some "audit" to solve the problem. They are claiming our pbx clockrate might be responsible. What could interefere with faxing in such a way? Could the telco have enabled some echo cancellation on their side? Thanks in advance for any insight,
