Yes, voice packets are given priority on the network IF your ISP has DQoS implemented and enabled. This is not assumed or standard on any networks I'm familiar with, and you'd be foolish to assume ISPs rushing out to benefit third-party VoIP companies when there's a push to roll out ISP-branded VoIP... Anyway, without DQoS, it's all best-effort. As noted above, given sufficient bandwidth, you'll hadly ever get jitter unless you saturate the pipe with up/downloads that preclude sequential voice packets.
