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 transmissions if enabled) and transmitted via another port/channel.
Three relay modes of operation are supported.
Mode 1: Use UDP packets and encryption.
Mode 2: Use UDP packets and encryption; use single UDP port.
Mode 3: Use TCP packets and encryption; Use single TCP port;
The mode 2 and mode 3 are the passive and the port use is assigned by the
RELAY SERVER.
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
