Google voice can't call

I give money, can't call! how to do?

It appears that you're right. I suppose Geph's udp relay is not working, so that you can't make or receive phone calls.

so how to do? i use v2ray can call

I bought three v2ray airports, they can call

who can help me

Can you try using the Singapore, Finland, or Canada exits? It might be that the other exits block BitTorrent and this also accidentally block other P2P traffic.
