I have setup a openvpn server on clound (digital ocean). and my vpn client connects from local internet.
My goal is to use SIP (VOIP) over the VPN and my SIP server is also the same OpenVPN server.
My VPN get connected successfully and I can ping server from client perfectly fine. and I can register SIP User on client successfully. But the issue is when i dial the number from client my voice start breaking and at the same time when call is connected I check the ping it show big delay first and then timeout.
Can any tell me whats wrong with my configuration.
