IPO behind Cisco Routers

[dphoneguy24]

Has anyone deployed IPO with SCN behind a customer's existing Cisco Routers - Frame Relay? I have deployed a SCN with 1 central site / 6 remote sites Frame Relay PVCs from remotes all point to point back to the central site sucessfully using IPO as the routers implementing FRF.12 and RFC 1490 - recommended implementation on IPO. I don't have access to the Cisco routers for this particular situation but the people that handle that portion are trying to tell the mutual customer that fragmentation should not be implemented. I have never had issues with the data flow or QoS for VoIP with the above mentioned IPO 7 site rollout. We have been fighting QoS though behind the Cisco routers with this other one. The basics are the same... one site has a 512CIR the remotes 128CIR. Anyone have any suggestions? They would be much appreciated.

thanks,
