“Network Info”).
z Go to 『1.Network』 and use【＋】and【－】to navigate active network configuration:
host IP, MAC address, active primary DNS IP and optional secondary DNS IP (In that
order).
z If your host IP is within any of the listed ranges, then your IP SIP Phone resides on
LAN, otherwise, it locates on public internet.
i. 10.0.0.0 ~ 10.255.255.255 (10.xxx.xxx.xxx).
ii. 172.16.0.0 ~ 172.31.255.255 (172.16.xxx.xxx ~ 172.31.xxx.xxx).
iii. 192.168.0.0 ~ 192.168.255.255 (192.168.xxx.xxx).
Note: if your host IP is 127.0.0.1, you should reconfigure your network to acquire a valid IP.
2. Public Internet Configuration
z 『 Main Menu』=>『6.Network』/『4.NAT & firewall』/『2.UDP traversal』
z Enable “1.Full access” by press 【HOLD】
3. LAN Configuration to Traverse NAT/Firewall
There are basically 2 options for CPE to traverse NAT/Firewall:
(a) Option 1: Set up a static route in the NAT gateway (Recommend)。
(b) Option 2: Use STUN to measure out ports.
Please adopt suitable option based on your network configuration.
Note: some SIP ISPs may provide SIP-aware router (NAT/Firewall) for their customers.
When you use a SIP-aware router, NAT detection should be set to "Off" as if you
were on the public internet and the configuration is the same as “Public Internet
Configuration”: 『6.Network』/『4.NAT & firewall』/『2.UDP traversal』/『1.Full
access』, which is to say that you do not have to worry about the NAT, nor firewall.
3. Option-1: Contact your network administrator to configure your NAT/Firewall route.
z Contact your network administrator and acquire at least 7 consecutive UDP ports
mapped from the NAT to your IP SIP Phone.
For example:
i. NAT IP = 210.95.168.1 (you may detect your NAT IP by STUN from 『Main
Menu』=>『6.Network』/『4.NAT & firewall』/ 『1. STUN』/ 『2. Diagnose
NAT』)
ii. The network administrator has mapped UDP port 10101~10107 from NAT to
your IP SIP Phone 192.168.1.50.
Note 1: Since the network administrator has to configure the NAT/firewall to map
those UDP ports to your IP SIP Phone, thus you should use static IP instead of
DHCP as your network configuration. Otherwise you take the risk that the IP
SIP Phone would get a different IP from the currently set into the mapping
when it reboot and re-get its IP by DHCP.
