[tlug] SIP Provider

["Stefan A." <stefan_a@example.com>]

Hi guys, I am looking for a SIP provider that offers reasonable prices
and decent service for phone calls to Japan and I was hoping you may
have a suggestion. I have tried Diamondcard and Dellmont before, but
haven't been quite satisfied with their quality of service (connection
drops, echo, long delays etc.), so I was curious to hear what you are
using? I intend to make phone calls primarily from Europe to Japan
(and the other way around on occasion), either through software or via
local access numbers. Hope somebody has a recommendation :-)

Thanks for your help!
Stefan
