[cisco-voip] T37 fax problem

[Mustafa Yadav]

Hi,

We are running T37 fax in several branches.But 3 of them are getting
most of the fax pages corrupted.I checked the config with the others
.Everthing seems correct.IOS is
flash:c2800nm-advipservicesk9-mz.124-15.T9.bin and dsp is 9.4.910.

So the fax pages succesfully taken and I can see tiff files in the
mail server but mostly big chareccters and half  blank page.
What could be the reason?
