Are you using passthrough or relay? Our rightfax is configured for T.38 version 0 and it works well. You can see it in the SIP settings in the Brooktrout Configuration Tool. I don't think our rightfax version even does ECM although I think I read the newer ones do which could also cause problems.

Subject: [cisco-voip] right fax sr140 transmission errors

we just moved to a Virtual Right fax with the new virtural SR140 fax board.  Thus we are now doing a SIP trunk to call manager.

we are getting a lot of transmission errors.  anyone have any ideas?  the T1 CAS is coming in on a 3845 with NO controller errors.

I think maybe it has something to do with transmission speed or ECM but does anyone know if you can turn that stuff off?  any other thoughts?

TIA

Scott
