No need for you to be corrected. Jitter is indeed variation in delay. But tunnelling iax or rtp through a tcp-based tunnel will exactly result in variable delay. When a packet on the tcp level is lost, tcp will retransmit it. In the meantime - whilst the missing packet is detected and recovered, all the packet flow stops for 2xround-trip+slow-start so the receiver sees a spike in delay, ie jitter.
