Voice is actually remarkably tolerant of pure latency. While 60ms of jitter makes a connection almost unusalbe, a few hundred ms of consistant latency isn't a problem. IIRC (from my college days when ATM was the new, hot technology) you have to get up to around a second of latency before pure-consistant latency starts to break things.
I would say most people start to get trouble when talking to each other when the RTT exceeds around 500-600ms.
I mostly agree with http://www.cisco.com/c/en/us/support/docs/voice/voice-quality/5125-delay-details.html but RTT of over 500ms is not fun. You basically can't have a heated argument/discussion when the RTT is higher than this :P
