voip provider blocked, voip blocked by isp.

[elios115]

i am in a country where my ISP blocks voip calls of all kinds.
my network is behind a symmetric udp nat as per the stun checking.
the 3CX tunelling solved the problem of connecting remote extensions. it is great
but if i added a voip provider to my phone server, i cant make outbound calls through my voip provider since it is blocked by my ISP.
is there any way to route the connection to the voip provider ONLY through any vpn services such as securitykiss or any paid vpn service that will connect to a remote server in the USA?

any thought about this option?

Hello,
What you need to do is to find out the range or ranges of IP addresses that your VOIP provider uses. Then, use static routing to route through the Ethernet interface allocated for the VPN.

The Ethernet interface should only have the IP address itself, subnet mask and DNS. No gateway. Add your persistent routes using the route add command. Check them all using the route print command. See http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sag_tcpip_pro_addstaticroute.mspx?mfr=true to learn about setting static routes in Windows.

Kind regards
Richard

I was using bvpn when I was in Dubai as I suffered from Geo-blocking there, and I managed to make VOIP calls without any interruption and unfortunately they are banned also in my home town Egypt https://www.vpnanswers.com/egypt-bans-voip-bvpn-helps/
