I’ve added Future Nine to the list of servers whose ping time I monitor. Even though they are a US based company they have a sip server in Europe and incoming numbers in the UK for only $5/month.

So if you’re in the UK/Europe and looking for a voip provider with competative prices it might be worth checking them out.

You can see the current ping from my servers to theirs here – http://sysadminman.net/uk-voip-vps-pings.html
