Appendix A : Troubleshooting the InterPhone
1. How do I know if my configuration is successful?
After you complete Basic Setup, on the LCD panel you will see a steady sign on PSTN Mode
or a steady @ sign on I-PHONE Mode.
2. If my sign (on PSTN Mode) or @ sign (on I-PHONE Mode) is not steady,ie,flashing,
what should I do ?
Check the Basic Setup Items: IP Address, Gateway IP Address, Subnet Mask. You may get
the above information from your ISP or MIS personnel.
3. Do I need a real IP address to configure my InterPhone?
Yes! You need to assign a real IP address to your InterPhone. Moreover, this IP address
cannot be shared by other equipment on the LAN.
4. If my ISP assigns a dynamic real IP to me, what I should do?
Some broadband operators assign dynamic IP addresses to subscribers. InterPhone supports
DHCP function. Make sure the dynamic IP is real IP. Go to DHCP setup item and enable this
function.
5. If there is a DHCP on the LAN, what I should do?
InterPhone supports DHCP function. If there is a DHCP server on your network environment,
simply go to DHCP setup item and enable this function.
6. What kind of network interface does my InterPhone support?
InterPhone provides value added voice communications for broadband or wideband users. It
supports Ethernet interface from Leased Line, xDSL and Cable Modem.
7. There is a firewall on my LAN. Will it block my voice?
If there is a firewall on your LAN, it blocks the voice packets, too. At this moment, the remote
party can hear your voice but the remote party’s voice will be blocked by the firewall. Please
advise your MIS personnel to open UDP 1101 port and TCP 1100 port so that the voice data
can pass through.
8. If I have a PBX in my office, can I share the InterPhone so that everyone can use it?
The home version of InterPhone is designed for individual users. We don’t recommend you
equip home version of InterPhone on your PBX system. The impedance might cause noises.
We recommend you to use the other DSG Ethernet Phone Device “InterStar” for PBX
application.
9. Can I upgrade my InterPhone?
Yes! DSG Technology keeps on providing more functions to users. To download the latest version,
simply go to SYSTEM SETUP and enter AUTO UPGRADE item. Press ENETR button. InterPhone will
download the latest software for you automatically.
