New VoIP deployment. 100+ phones, VG-224 with roughly 12-14 fax machines. Call Manager 7. VG-224 is at the same location as 2811 Gateway servicing the PRI. All fax calls come in and leave the PRI. T.38 between 2811 and VG-224.
Had some issues with T1 timing that was resolved with Cisco TAC (we missed a timing config on the 2811). Fax transmission has stabilized. However, speeds are still in the tank. A 24 page document took almost 40 minutes in once case. Any thoughts about what we might be missing? Are there any tips or tricks some of you who have been through this might be able to share with us?
