Airvpn + voip fail

[criminaldamage 0]

Hi,

 

I have a problem with Airvpn + voip. My setup goes as: Android with OpenVPN (in config is selected best latency server and UDP option) > Zoiper android VOIP app which connects to callwithus.com voip service. I choosed airvpn for best speed recommendations. VPN I had before was slower and I could not call with vpn/voip. Voip is configured well (I guess, maybe needed some options for VPN) because if I turn off VPN, voip works just fine. Anyone has experience, suggestions, solutions how to make this setup working? Because for now it just dead silence - connection speed is too low I guess.

 

Thanks,

VoIP needs open ports to work. If your VoIP provider didn't change the defaults, 5060 (SIP) and some other ports (RTP/RTCP) must be opened - improbable to make it work because one port can only be assigned to one account, and there may be more than one user trying to do so.
