Use the built-in answering system to record your messages
Your Voicemail service can bundle in your telephone plan. As such, you would need to contact your telephone service provider to disable it.
*TIP: Can I switch back to Voicemail service if I want to?
As long as your telephone plan includes the Voicemail service, you can still re-enable it through your service provider.Use the voicemail service to record your messages
Simply turn off the Built-in answering system at any time, and you can use the Voicemail service only.Use both the Built-in answering system and the Voicemail service to record messages
By default, the Voicemail service is usually set to answer after 2 rings, while your Built-in answering system is set after 3 rings. Please check with your telephone service provider to learn how to set your voicemail settings.Suggest to set your Built-in answering system to answer calls at least 2 rings earlier than your Voicemail service. In other words, if your answering system sets to answer after 3 rings (by default), then you need to set the Voicemail service to answer after 5 rings.
What happened is that if you on a call or the answering system is already recording, and you receive ANOTHER incoming call, then the third caller is able to leave a Voicemail message.
On the other hand, if you are not on a call nor the answering system is recording, the incoming caller can leave a message directly to the Built-in Answering system.

If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause static/noise, squealing (similar to fax tones), caller ID disruption and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.
In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.
Please contact your service provider to obtain DSL filters and installation information. -
Tip 2 of 8
Other electronic products (i.e., 802.11 wireless networking products, radios, radio towers, pager towers, cell phones, intercoms, room monitors, televisions, personal computers, kitchen appliances and other cordless phones) can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices. -
Tip 3 of 8
Move the closer to the base. The operating range may vary with environmental conditions and time of use. There may be places within your environment that a cordless device will not work well. If the problem only occurs in certain areas of your environment, you can conclude that there is nothing wrong with the headset. -

To get better reception, try moving the telephone base to higher location. Relocate telephone base near a window if using telephone outside. -
Tip 5 of 8
If your phone shares a power outlet with a modem, or if it is plugged in to a shared surge protector, try plugging the phone (or modem/surge protector) in at a different location. If this solves the problem, re-locate your phone or modem farther apart from one another, or use separate surge protectors. -
Tip 6 of 8
Disconnect all other equipment on the phone line, as the problem may be caused by a different product than your cordless phone system. Reconnect your equipment, one unit at a time, until you determine the cause of the problem. -
Tip 7 of 8
If you have connected this telephone to a phone jack that has not been used before, or that has not been used in sometime, there may be problems with this jack that you are not aware of. Use a telephone jack that you know is in proper working order. -
Tip 8 of 8
If the other phones in your home are having the issue, the problem could be related to the telephone wiring in your home, or with your local telephone service. Please call your service provider for further assistance.

My telephone handset appears to be dead. What should I do?
-
Tip 1 of 10
If your handset responds in any way (beeps, displays a message on the screen, etc.) then it is not dead. Please review the Frequently Asked Questions list to check for a more specific symptom to your problem.
A common cause for dead handset symptoms is a dead battery. We recommend that you initially charge the handset battery for 16 hours. If the handset does not hold a charge or seems dead, we suggest the following:
• Please verify that the handset battery(s) is securely plugged into the back of the handset.
• Check that there is power to the base and charger. If there is power and the handset is cradled face up, the CHARGE light on the handset will be on, and/or the battery icon will be displayed.
-
Tip 2 of 10
Confirm proper installation of the telephone base power supply and handset battery. You should only use the VTech power supply provided with your telephone. Make sure the power supply is not connected to an electrical outlet that is controlled by a wall switch. Confirm that the electrical outlet that the telephone is plugged into is working. -
Tip 3 of 10
Make sure you are using the battery supplied with your phone. If you are replacing the battery and you need assistance, refer to our VTech Battery Finder. If a battery for your model is unavailable, you can search the internet using the key words cordless phone batteries for an on-line supplier. If you prefer to purchase locally, you can look for a replacement battery at your area consumer electronics retailers. It is recommended that you take your present battery with you to insure your replacement is the correct size and has the correct plug (where applicable) and specifications. -
Tip 4 of 10
When placing the handset in the base or charger, confirm that the charge contacts are making a good connection. The charging battery icon is displayed and, on selected models, the CHARGE light illuminates on the handset while it charges.
You should allow 16 hours to fully charge the handset battery. For optimum daily performance, return the handset to its telephone base or charger when not in use. -
Tip 5 of 10
Please make sure that the cords (power and telephone line) are plugged into the channels on the bottom of the base. If the cords are not properly installed, the base will not sit level and the phone may not charge properly. -
Tip 6 of 10
Dirty charge contacts on the telephone base and handset could prevent the batteries from charging. Clean the handset and base charge contacts using a pencil eraser or a cloth to eliminate deposit accumulation. -

If you prefer to purchase locally, you can look for a replacement battery at your area consumer electronics retailers. It is recommended that you take your present battery with you to insure your replacement is the correct size and has the correct plug (where applicable) and specifications.

[Background]
• VoIP box connected via SIM/ LAN connection.
• Some VoIP boxes have displays and some not. While displays show steady ON and ready, you might still experience with no dial tone sound/ display Line in Use.[To Reset]
• Some Power off button does not fully power off the unit. It only put the VoIP box in standby mode. To truly power off, unplug the power adapter of your VoIP box.
• Disconnect all devices from the box. After a moment, reconnect your power adapter, and then press power button to turn ON.
• Wait until the VoIP box is steady ON and ready.
• Connect your telephone cable from your Telephone base to your VoIP box.REMINDER!!!
• Make sure you didn't connect the telephone cable from the Telephone wall outlet to VoIP box telephone port!!! Doing so will not damage the device, but it will affect the call function and becomes unusable. This is why you experience no dial tone, Line in Use with busy tone, etc.
• During power outage, your landline phone will not be available since it requires external electric power despite your VoIP box has a backup battery.If this situation persists, contact your VoIP / VoIP box service provider for further support.
