Hi
I have setup T.37 fax on a cisco 2651xm with a AIM-30 most faxes seems to come through fine but high graphic ones or pages with allot of dark detail seem to come through all screwed up or even missing the bottom half of the page.
The strage thing is this might happen to page one but page two which has just text on it will come through ok so the connection is not dropping after the bad page.
Can anyone please help, as i have given up with ATA boxes and we need a working fax solution without the expense of VG200...

put "image resolution super-fine" in your mmoip dial-peer and try again. This works for me pretty well on a 5350.
If it does not work, post your config.

Maybe the issue is not in the T.37 fax-to-mail (TIFF) conversion, but with the faxes at all. Try to send a fax from a fax machine to a fax machine via VoIP. If the quality is bad, try this command under the voip dial-peer:
fax-relay ECM disable
