From the developer:
The SIP Proxy Tunnel can combine all SIP (signaling) and RTP (media) VoIP Packets from one location (typically a remote office) and deliver them to and from another location (typically the PBX Server) using a custom TCP protocol. The program simplifies Firewall configuration at both the remote and the PBX location, resolves issues of NAT Traversal and more.
