Signaling NAT Traversal
– NAT Traversal is an algorithm designed to solve a
common problem in TCP/IP networking in establishing connections between hosts
in private TCP/IP networks that use NAT devices. This parameter only sets the
NAT Traversal mode for VoIP signaling. The 2 methods supported are
STUN(RFC3489)
and
Relay Proxy
. A STUN Server is required for
STUN(RFC3489)
.
Relay Proxy
mode is a proprietary NAT protocol and it requires the use of our
Relay Proxy Server. All VoIP signaling packets are encapsulated (encrypted for
more secured transmission if enabled) and transmitted via another port/channel.
Up to 4 backup Relay Servers are supported. Once the designated Relay Server
fails, the next available Relay Server on the back up list will be used. Once the
designated Relay Server resumes operation, it will be used instead of the back up
Relay Server.
Note: For Service providers, RELAY Proxy software is available at no charge. Please
contact your supplier for support. For end user, please contact your service provider to see if
this feature is available.
4.3.3.3 Media Settings
Once a VoIP call is established, the Media channel is used for voice transmission. The
