I don't think you'll find a definitive answer as it greatly depends on the application being deployed. Phone services are really just another data application on the network. In general, data applications can withstand greater latency/jitter/packet loss than voice. Applications that use TCP for transport can retransmit packets that are lost. This doesn't work with voice packets. Latency and jitter may cause the application's performance to be degraded, but it will still work. Too much latency or jitter will cause voice quality to be unacceptable. So, the latency/jitter/packet loss requirements for a given application will depend on the application's real-time nature and users' performance expectations.
