Hi Adrian, If we use openvpn or other vpn then we have to handle vpn connection from client and also from server for each user. We want single server side component for encryption and decryption so our voip packet can not be parsed by third party. We want what opensips server and rtpproxy server can decrypt the signals. So can you please tell me where can i find files to send and receive SIP signals in opensips?
