Remember that VoIP uses short packets, and you cam always recognize Ack and Tcp packets which should not be disrupted. Jitter does not slow down network, except if it interacts with RTT calculartion in TCP/IP.
Alexei: Apologize for the delay in getting a reply to you. Regarding your comment on jitter, FLATLY or more generally, if introducing jitter is likely to complicate operational matters elsewhere in the network [whether this complication manifests within one's own network or in another - to which one is inter-connected] I would be inclined to say this effects the overall performance... I did not mean to take more of your time on this. But, I wanted to merely clarify. Best, Robert. -------
