you have to look for “NAT”, “PAT” or “Port Forwarding” description of your
network device. Please, find below an example of router configuration for
the router labelled as ‘WEST’:

NOTE: When calling with Prodys Proprietary Protocol V3 is not
necessary to configure NAPT (Port Forwarding) in the router placed at
the caller side, only at the callee side.
• The following step is to define a range of ports to be used by the unit for
its IP communications which matches the port forwarding range defined
27
The First Port number can be any available port number for the gateway. We recommend to
agree with your network administrator which the port ranges are fully available for the codecs for
not to overlap with other IP services of your network.
28
Map port “0” means for most of the router configuration that the external port number matches
the port number for the local area network. Given an example: an incoming request from the
WAN interface to the port number 50073 will be forwarded to the codec B on the same port
number 50073. In other case one port by one must be defined according the Prodys Family User
Manual.
29
Ports 5X60 and 5X04 in this example are only used in case of using SIP protocol.
