XP Is there any way around blocked VOIP

[Soulactings]

So as you know VOIP is blocked in Egypt which makes me unable to use mumble which makes me unable to talk with other people or hear them so is there any way around this, And yes I have tried using proxies the first time it worked but now it just says "connection timed out" or "failed to auth proxy" So is there any way I could get around this without using proxies or is there any way I could fix the proxy to not say that?

And yes I am using good proxies from VOIP Unblocked countries.
