As far as i read the TCP transport is not good for the voice: http://www.cs.columbia.edu/techreports/cucs-033-04.pdf http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4607363 http://portal.acm.org/citation.cfm?id=1375457.1375464 But it's also true that it can goes over proxy server where UDP does not goes trough.
