On-ramp faxes corrupt, TIFFs incomplete/scrambled

Hello Team,

i cannot receive onramp-faxes properly anymore.
They are corrupt, after the half page the sent TIFFs are just rubbish/unreadable/incomplete.
Looks like i had sort of timing/clocking-problem, had this before with PSTN->FXS-connections and attached faxes, but...i did all i did there to solve this problem.
I have set the clocking options as seen below, usually solved these problems. Not in this case.

BTW i have no timeslips or anything like that:
voip-rt-2#sh controllers e1
E1 0/0/0 is up.
  Applique type is Channelized E1 - balanced
  No alarms detected.
  alarm-trigger is not set
  Version info FPGA Rev: 08121917, FPGA Type: PRK1
  Framing is CRC4, Line Code is HDB3, Clock Source is Line.
  International Bit: 1, National Bits: 11111
  Data in current interval (846 seconds elapsed):
     0 Line Code Violations, 0 Path Code Violations
     0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
     0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
  Total Data (last 24 hours)
     0 Line Code Violations, 0 Path Code Violations,
     0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,
     0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

My configuration as below worked wonderful on our former voice router, an 2811 with three BRI-interfaces.
We have moved our PSTN-connection to our new 2921 with an E1 controller. Also the configuration regarding onramp-faxes.

Any helpful input on this problem would be appreciated, since users complain about it, everybody liked this feature before.
Otherwise we would have to implement another faxsolution...the onramp-solution before (as long as it worked!) completely fitted our needs.

And i really want to stay with the former solution. On the new gateway, for sure.

Many thanks in advance,
Andreas

Try modifying the image

Try modifying the image encoding. I had TIFF files coming through with some of the content distorted or squashed together.. I found changing to the Modified Huffman (MH) image encoding sorted everything for me.

Make this change under the MMOIP Dial-Peer

"image encoding mh"

Other options are

Modified Modified Read (mmh)
Modified Read (mr)
Passthrough

 

Thanks

Ben

Many thanks, Ben, this seemed

Many thanks, Ben, this seemed to solve the problem here too.

No idea why i had no problem with this on the old gateway, but...i´m finished with trying to understand everything in IT meanwhile ;)
