the "yet" is about modifying an active RAB -- IIUC for handover that wouldn't 
be needed.

If we implement handover on 3G:

- intra-RNC handover would at most notify the CN after handover occurred, the 
RNC should 'hide' it from HNBGW and upwards.
- inter-RNC / inter-RAT handover would establish a brand new RAB on another 
RNC/BSC/... and then assign the UE to that, so there wouldn't be a RAB 
modification.

A voice announcement should come from "behind" the MSC's MGW hop, so the active 
CS RAB should not need modification for that.

I hope I understood correctly...
