SIP Firewall Traversal
Eyeball AnyFirewall™Server provides a scalable NAT and firewall traversal solution for SIP end-points based on IETF standards and drafts such as STUN, TURN and ICE:
  • STUN helps an end-point to discover whether it is behind a NAT/firewall and determines the public IP address of the firewall and the type of firewall. It is helpful in establishing peer-to-peer calls between endpoints where at least one of the end-points is behind a NAT a or firewall.
  • TURN provides a far-end NAT traversal technique where a media relay server connected directly to public Internet is used to help media transport between end-points.
  • ICE provides a SIP offer/answer model for end-points to exchange multiple candidate IP addresses and ports (such as private address and TURN server address) so that end-points can always establish a connection between
    them.
For TURN, Eyeball AnyFirewall Server supports UDP and TCP transport. It also supports HTTP/HTTPS tunneling for all communications such as SIP signaling and media data.
