STUN protocol.

Description
NAT Public IP
Enable NAT
NAT IP/Domain
The IP address used by VoiceCom90 should be a virtual
address. Further more, users must set the Virtual Server
Mapping in the NAT Server (A virtual server is defined as a
Service Port, and all requests to this port will be redirected to
this specified the server IP address).
Enable STUN Client
Using STUN protocol prevents problems with setting the IP
sharing function, but some NAT do not support this protocol.
STUN Server IP/Domain
STUN Server Port
Enter the STUN server IP address and Listen Port number.
You can set 2 STUN server spread by semicolon.
Enable UPnP Control Point
Enable VoiceCom90’s IP traffic to pass through a NAT server.
Note:
The default port is listed below:
Listen Port (UDP): 5060
RTP Starting Port (UDP): 9000~9003 (Listen Port used for telephone communication).
Http Port (TCP): 80 NAT IP/Domain: Enter the NAT Server IP address (Real External IP
address of NAT Server) then fill in the URL (Uniform Resource Locator). If using DDNS,
please refer to the next setting item
DDNS
These settings are only necessary when VoiceCom90 is set up under a NAT that uses a dynamic
IP address and do not support DDNS.
First of all, you need to apply an account from one of the servers. VoiceCom90 allows user to
choose one of DynDNS, TZO, 3322.org, PeanutHull or a private server.
