The first softphones based on Adobe Flash are starting to appear. Previously I've written about Pudding Media, which ships a flash based phone, and Tom Keating has written about flashphone.ru. The advantage, of course, of shipping a flash based widget, is that it can run on so many platforms. In conversation at VON last week, however, one vendor I spoke with still favours Java based softphones because of latency and jitter issues. Current generation flash phones are apparently TCP based, and not UDP. Should be sufficient in a PBX environment, in any case.
