I'll be in the UK again in November. I understand some people in Manchester had previously run an evaluation of free softphones and I would be interested to know if there would be interest in running a workshop on this, looking at what has improved and tools for analyzing such problems.
In particular, I'd be interested in looking at the experiences people are having with mobile apps like Lumicall[2] and Conversations[3]. Mobile apps typically assume bad networking and try a little bit harder to ensure end-to-end connectivity.
Regards,
Daniel
