Hi, I live in Netherlands, and your server seems to be located in California, USA, somewhere right beneath me...
Question is: are the actual voice call streams routed via your server? Or just the connection. It does not make much sense to call my fello buddy in NL via your service, as if it is routed via US, it would be extremely slow and poor quality... Or is it?
Do you have any European access points?

there are many factors that can contribute to packet loss and latency in a VOIP call; distance is just one and not always the biggest factor. the best way to judge the quality of calls through a certain network is make test calls; as opposed to trying to determine call quality by the technical aspects(there are just to many variables to get an accurate conclusion that way)
it could be that because of the way two specific ISP are connected to each other that call quality could be much better on a call half way around the globe than one just down the street.
p.s. i do believe that the protocol conversion would require that calls be proxied through the servers. an exception may be if a SIP call get forwarded to another SIP URI(or PSTN termination partner) after 20 seconds.

Satphoneguy is pretty correct in his answer to you, converting between different VoIM protocols require media streams to pass through our server too, due to different codecs and RTP/ICE implementaions. Yet, the average latency between US and Europe is not high (200ms) and usually it gives quite good/acceptable voice quality. So you better make some tests and let us know your results .
