“UDP traversal” configuration. You may detect your NAT IP by STUN from menu-“Diagnose NAT”
(please fill in only the IP, excluding the diagnosed SIP port).

Note
1. You should also map the SIP signaling port, RTP port base and RTP port range
used for media stream from NAT to the phone to enable UDP traverse through
NAT / Firewall (if there are several phones reside under the same NAT, their SIP
and RTP ports must not be overlapped since they all share the same NAT
resource).
2. If your NAT uses dial-up modem or connects to the WAN via ADSL by PPPoE,
then the IP of your NAT may change whenever it re-dials up. Please synchronize
it if the NAT does not come with a fixed IP. Besides, you may detect your NAT IP
by STUN from menu- “Diagnose NAT” and re-configure the new NAT IP into
menu-“Static NAT IP”.
