Troubleshooting
If you have difficulty with the telephones, please try the suggestions below. For customer service, call +44 (0)1942 26 5195 or email vtech@corpteluk.com.
For corded telephone
Question 1. The telephone does not work at all.
Suggestions
· Make sure a Cat-5 network cable is plugged into the LAN port of the telephone base and the network wall jack with Power over Ethernet (PoE).
· Unplug the Cat-5 network cable from the network wall jack. Wait for approximately 15 seconds, then plug it back in.
· Disconnect the telephone base from the network wall jack and connect a different working telephone. If the other telephone does not work, the problem is probably in the wiring or network server.
2. There is no dial tone.
· Try all the above suggestions.
· The Cat-5 network cable may be defective. Install a new Cat-5 network cable.
· Make sure your network is providing Power over Ethernet (PoE).
· Disconnect the telephone base from the network wall jack and connect a different working telephone. If there is no dial tone on this telephone either, the problem is in your wiring or network server.
· Make sure the initialization and system registration process completes. The speakerphone key blinks twice every second if there are errors with the initialization and system registration process.
3. I hear other calls when using the telephone.
· Disconnect the telephone base from the network wall jack and connect a different working telephone. Check your server settings. If calls are still not clear, the problem is probably in the wiring or network server. Contact your telephone service provider (charges may apply).
4. The Speed Dial key does not work at all.
· The Speed Dial key may not be properly programmed.
EN – 15
Question 5. I cannot dial out.
6. The telephone cannot register to the network server.
7. The telephone does not ring when there is an incoming call.
Suggestions
· Try all the above suggestions.
· A prefix may be required for dialling some internal or external calls
· Make sure there is a dial tone before dialling.
· Check your server settings. If other telephones in your hotel are having the same problem, the problem is in the wiring or network server. Contact your telephone service provider (charges may apply).
· Make sure your network is providing Power over Ethernet (PoE).
· Make sure the initialization and system registration process completes.
· If there is an error during the initialization and system registration process, the key flashes twice every second. Disconnect the Cat-5 network cable from the network wall jack and connect it back into the network wall jack with Power over Ethernet (PoE) to start the initialization and system registration process again.
· Make sure the Cat-5 network cable is plugged into the LAN port of the telephone base and the network wall jack with Power over Ethernet (PoE).
· Check your server or telephone administrative settings.
· If other telephones in your hotel are having the same problem, the problem is in the wiring or network server. Contact your telephone service provider (charges may apply).
· Other electronic products such as HAM radios and other DECT telephones can cause interference with your cordless telephone. Try installing your telephone as far away as possible from these types of electronic devices.
· The Cat-5 network cable may be defective. Install a new Cat-5 network cable.
EN – 16
Question
8. There is interference during a telephone conversation.
Suggestions
· If your telephone is plugged in with a modem or a surge protector, plug the telephone (or modem/surge protector) into a different location. If this doesn’t solve the problem, relocate your telephone or modem farther apart from each other, or use a different surge protector.
· Disconnect the telephone base from the telephone wall jack. Plug in a different telephone. If calls are still not clear, the problem is probably in the wiring or telephone service. Contact your telephone service provider (charges may apply).
· If other telephones in your hotel are having the same problem, the problem is in the wiring or telephone service. Contact your telephone service provider (charges may apply).
