Opteron vs Xeon in VOIP hosting

[spicypixel]

Just asking if anyone has had experience running VoIP such as Ventrilo or Teamspeak on both platforms and can compare.
Busy working on a few 1U racks for VoIP reselling and I can't find any sort of benchmark/comparison of running this kind of work load on the two archetectures.
Guess the choice is if a higher clocked 4c8t xeon will do better than the relatively lower clocked 12 or 8 core opterons.

That said my gut feeling is that the more numerous real cores on the AMD will be preferential.

Any help would be appreciated.

ps: we're talking about tens of 24 slot servers

Good timing, and I'm merely doing some on the side consulting and I happened to be approached on this topic and couldn't qualify an answer to asked here. He did indeed go with the Dell R210 which seems to be the de facto 1u1s solution (albeit noisy but its in a datacenter so its irrelevent)
And yeah I'm aware at the ability to make a profit on these things, and yes it'll be bundled with other products as opposed to a solo VoIP venture.

Thanks for the info.
