Hampton Articulation adds SIP-compliant VoIP to Palm devices {Engadget Mobile}

Aug 25th 2006 6:08PM Didn't work on my Treo 650 over EDGE. I placed echo test calls but never got any audio echoed back to me. I tried all the suggestions listed in http://www.hamptonsoftware.co.uk/articulation/novoice.shtml except the NAT setting stuff. Since I have a Cingular MEdia Net plan, I can't accept inbound TCP or UDP, so maybe that's the problem.
