I need a tunnel to connect remote SIP phones (Hardware or software) to asterisk PBX from firewalled lans with these features:
- Encryption of VoIP data.
- Traversal of any NAT and any Firewall.
- Data compression levels over the tunnel to minimize throughput.
- Use of HTTP or HTTPS or any other well-known port to transport VoIP data.
- Customizable security levels with different encryption keys lengths and many encryption algorithms.
