There are probably other issues as well. Skype works fine over Tor. Depending upon your circuit, voice calls can be very laggy. Hrmm.. According to: http://www.secdev.org/conf/skype_BHEU06.handout.pdf Skype does TCP if UDP attempts fail. However it appears to encode your IP address in messages. Sort of defeats the purpose of Torifying it. Probably the case with a lot of voice clients, unless you can find a way to get them to not discover your IP...

Skype Call Traced
Skype Call Traced Kobi Alexander fled the United States ten days ago. He was tracked down in Sri Lanka via a Skype call: According to the report, Alexander was located after making a one-minute call via the online telephone Skype service. The call, made from the Sri Lankan capital Colombo, alerted intelligence agencies to his presence in the country. Ars Technica explains: The fugitive former CEO may have been convinced that using Skype made him safe from tracking, but he -- and everyone else that believes VoIP is inherently more secure than a landline -- was wrong. Tracking anonymous peer-to-peer VoIP traffic over the Internet is possible (PDF). In fact, it can be done even if the parties have taken some steps to disguise the traffic. Let this be a warning to all of you who thought Skype was anonymous. http://www.schneier.com/blog/archives/2006/08/skype_call_trac.html http://ise.gmu.edu/~xwangc/Publications/CCS05-VoIPTracking.pdf
