login into the Web User Interface, open the Bowser (IE/FireFox) and input IP address.
Q: I forgot the administrator password. What should I do?
A: Press the Reset button on the rear panel for over 5 seconds to reset all settings to default factory
values. Then you can use the default Username/Password to Login Web UI.
Q: Why is it that I can ping to outside hosts, but not access Internet Web sites?
A: Check the DNS server settings on your PC. You should get the DNS servers settings from your ISP.
If your PC is running a DHCP client, remove any DNS IP address setting as the router will assign the
DNS settings to the DHCP-client-enabled PC.
Q: What is the maximum number of IP addresses that the DHCP server of the WATA can assign
to local PCs?
A: The built-in DHCP server can support 253 IP addresses for local network usage.
Q: Why can I call out by WATA?
A: Please look at the system information and line status pages check your WATA is registered to the
SIP Proxy Server(ITSP), and check your Internet works fine. You must have a SIP account or know the
other ATA/Gateway IP/Domain Name. Only then you can make a VoIP call.
Q: I can't use web Interface to setting WATA.
A: Please check your PC is connected to the WATA LAN port and that your PC and the WATA are in
the same Subnet. If you PC is not in the same Subnet, you can't Login into the WATA Web interface.
Else you let your WATA on Public Internet (Public IP address)
Q: Why does the one way talk happen?
A: Generally, one way talk happens when different codecs are used between the VoIP devices that are
making the call. Please check the settings and make sure the same codec are used.
Q: Why can I call out when the WATA under the NAT?
A: Most VoIP products have NAT Pass through problems. With SIP, most of the NAT Pass through
issues (about 80%) is solved. You can select STUN/Outbound Proxy/ Symmetric RTP to Pass through
NAT, and then you don't set any other setting (DMZ/Virtual Server) by router side. If you use
STUN/Outbound Proxy, you must have a STUN/Outbound Proxy Server to support. If they can't pass
NAT, please open the DMZ/Virtual Server by Router/NAT/Firewall.
