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.
Why do calls fade/cut in and out when I’m using this phone?

Tip 1 of 8
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
Move the handset 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 phone 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 phone. Consider trying a phone that operates on a different wireless frequency. -
Tip 3 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 4 of 8
To get better reception, try moving the cordless headset base to different location. Moving the base to a higher location often improves performance. Relocate the base near a window if using the headset outside. -
Tip 5 of 8
Excessive background noise will cause a speakerphone to fade in and out. Try controlling the background noise by turning off any audio devices near the speakerphone. Also, try to avoid interrupting the person at the other end of the conversation while they are speaking. If background noise cannot be controlled, you should terminate speakerphone operation and return to normal handset mode. -
Tip 6 of 8
When using a speakerphone, controlling background noise in your environment is essential. While you are listening to your party, press MUTE to temporarily turn your base microphone off. When it is your turn to speak, remember to press MUTE again to turn the microphone on. -
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.

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. -

Why am I not receiving caller ID on my phone?
-
Tip 1 of 6
Caller ID and Call Waiting ID are subscription services, available from most local telephone service providers. You must subscribe to these services in order for the features to work on your phone. Contact your local telephone service provider for more information.
In addition, your caller must be calling from an area that supports caller ID.
Both you and your caller’s telephone service provider must use compatible caller ID systems.
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 caller ID disruption, static, noise 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.
Caller ID and Call Waiting ID may not be available for every call. Common reasons are incompatibilities between your and your caller’s service, transmission errors and answering calls before the ID data is received. -
Tip 2 of 6
Caller ID data may not be displayed on your phone if you answer a call at or before the second ring. This would also apply to an answering device that "answers" the call at or before the second ring. -
Tip 3 of 6
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. -
