PORT SETTINGS
The SIP Port and RTP Port numbers are default at 5060 and 60000, respectively. The RTP port number must be even number. If you have more
than one VoIP phones under the same NAT router, it is recommended that different RTP port numbers be assigned to each of IP Phones.
You may need to program specifi c ports for the various devices on the router if the devices are differentiated and call forwarding problems occur
(e.g. in case of symmetric NAT).
In order to do this, according to the router model, follow the instructions shown in http://portforward.com/routers.htm for VoIP applications.
CODEC SETTINGS
