Allow me to raise my hand and say "I am recieving this error" too.

However, I was not recieving this error until I changed my zaptel.conf from:

span => 1,0,0,b8zs,esf

to

span => 1,1,0,b8zs,esf

Before, when timing was set to 0, no errors but bad faxes using spandsp.
Faxes would recieve fine but would be 8.5 x 10 in some cases.

Changed to timing 1 and now faxes are perfect, but I get the error. I don't
get the error that often. But I get it nonetheless..
