Central Voicemail (Unity) Delay requirements

[dvanzee]

Does anyone know of an acceptable delay (network ms/round trip) to move away from CUE to a central voicemail solution?

Hi, not sure right now of Cisco numbers. But we run several sites in Brazil remotely to a Unity 5 in Sao Paulo (soon be migrated to Unity Connection) in Buenos Aires. So far, we managed to use without issues and RTT showed by pings, about 40 to 50ms on MPLS network. Still have 3 CUE to migrate to central CUC8.
