Dynamic NAT IP
If your NAT uses dial-up modem or connect to the WAN via ADSL by PPPoE, then the IP of your
NAT may change whenever it re-dials up. If you choose “1.Notify on IP Change”, the phone will
notify you by sending an instant message into your inbox whenever it detects a mismatch between
the NAT you configured into menu-“Static NAT IP” and the one it auto-discovered by STUN. On the
contrary, if you choose “2.Auto-Update by STUN”, it would auto-refresh the NAT IP into
menu-“Static NAT IP” whenever it detects an inconsistency.
Default is “1.Notify on IP Change” and the detection interval is 20 minutes.

Diagnose UPnP
Detect the external IP of UPnP-capable NAT/Gateway/Firewall devices (support either WAN IP
Connection and WAN PPP Connection). It will search for UPnP devices and show its external IP.
If such devices existed, this terminal will open UDP/TCP mapping on NAT device for media
streaming and SIP signaling by UPnP as necessary; Otherwise if there is no such devices co-exist
(or turn off UPnP explicitly), it may show “Not found UPnP device”. Consult to your LAN
administrator for further information.
Í
Note
Either option requires a viable STUN server has been configured into
menu-“STUN server”
Í
Note
The UPnP mode must have been enable before you can dignose UPnP device
on your LAN.
