I have a hub router 7507 in the hub-and-spoke topology (remote locations connected via leased lines). For some locations 7507 router runs VoFR. All works well.I have tried to setup VoIP over Frame Relay for a new point in accordance with http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a00800a96b5.shtml. VoIP works well, but old VoFR has ceased to work. If entered 'no ip cef distributed' and 'no ip route-cache distributed' old VoFR works well again...Can I configure VoIP with dQoS and VoFR simultaneously on 7507 router?
