I only use the windows version and very rarely at that. There is a check box for monitor call quality and it shows the number of dropped packets, etc. I have never had a lot of luck with Skype. One of the problems is that it is designed to not be blocked. If you can't block it, you also can't give it priority in QOS. The best I could do was to force it to use a port for outgoing connections, but not incoming. As for what the ISP does, technically VoIP is illegal without a license from the MOC per the VoIP law of 2004. When the MOC tried to enforce it, there was such a public outcry that the next day they issued a "clarification" stating that the private use of VoIP, such as SKYPE was legal. Until then some of the ISP's blocked VoIP. Now they seem to leave it alone. I also have had similar problems with EchoLink, a proprietary protocol open only to licensed ham radio operators. For SIP type VoIP you need a latency (half ping time) of 150ms or less. I use a VoIP provider who has an average ping time of around 180ms, so the latency is about 90-100ms, which is quite good. If you do not mind that the connection is not encrypted (which I would never trust anyway), you can try using SIP. SIP requires a routing host in between. The easiest one to use is Free World Dialup. You go to their site and sign up, which gives you a free number (account). There are plenty of standard SIP hard and soft-phones you can use with it. FWD was created and is run by Jeff Pulver as an experiment to foster VoIP, which led to his being one of the founders of Vonage. He left the company long before they became popular.
