VoIP Encryption

Hi all,

Does anyone know any open source or tools to encrypt the VoIP packets (Singnaling/RTP)? Becuase some ISPs they are interpting the Voice packets. so i we will use the encryption it will be very hard for him to know the packets.

Already i tried with openVPN but the quality is still bad and the ISP interption is there.

I will be appricaite if anyone can tell me the tools or library to encrypt the packets.

Unfortunately, if openvpn didn’t work, not much else will. They weren’t interrupting a “voip” stream, they were interuppting an encrypted stream, that they really didn’t have an idea what it containted.

I suggest a new ISP if possible.
