Troubleshooting the Voice over IP Interfaces
I cannot connect to a VOIP-1-2-4-8 unit remotely via the Web GUI.
1. Check the power and cabling for the VoIP unit.
2. Be sure an IP address has been assigned to the VOIP-1-2-4-8 unit (this must be done in the
Windows GUI).
3. Make sure that the configuration was saved in the Windows GUI. Each pane in the
configuration software requires you to click on “Ok” before you “Save and reboot”.
4. Make sure that the latest version of Java is installed for your browser.
5. Make sure that the PC being used to access the VOIP unit remotely is on the same IP
network.
6. Make sure that a firewall is not blocking traffic the addresses and ports that the VOIP-1-2-4-8
use. Also, check to make sure that any routers in between are configured properly.
I cannot establish connectivity between two VoIPs in the system. I have phones that will not
connect in my setup.
1. Ping both VOIP-1-2-4-8 units to confirm connectivity to the network.
2. Verify the telephone connections. Check cabling. Are connections well seated? To correct
receptacle?
Are telephone Interface Parameter settings correct?
3. Verify phonebook configuration.
4. Observe console messages while placing a call. Look for error messages indicating phonebook
problems, network problems, voice-coder mismatches, etc.
The emergency phone consistently gets a busy signal or it is unable to dial out to the intended
phone.
1. Make sure the voice codecs are the same on all VOIP-1-2-4-8 units.
2. Verify phonebook and ensure that the calls are being routed to the intended box.
3. Make sure that the VOIP-1-2-4-8 unit is configured with a proper gateway address.
