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.

My speakerphone fades in and out. What can I do to fix this?
-
Tip 1 of 3
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 2 of 3
When using a speakerphone, you should be reasonably close to the base (or handset) in order to hear and be heard. The optimum distance will depend on room acoustics and noise levels. It is always a good idea to control ambient noise in your environment when using a speakerphone. -

Tip 1 of 7
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 4 of 7
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 5 of 7
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 6 of 7
You may have a line problem. To test for a line problem, test your unit at another location such as your neighbor’s or relative’s house. If your unit works at another location, contact your local telephone company. -

Why am I not receiving caller ID on my phone?
-
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.
How can I improve the sound quality on my cordless phone?
-
If your handset has a CHANNEL (or CHAN) button, press it in order to improve the sound quality. You may need to press the CHANNEL button more than once.

Electronic products (i.e., 802.11 wireless networks, radios, radio and 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.
Appliances or other cordless phones plugged into the same circuit as the telephone base can cause interference. Try moving the appliances or telephone base to another outlet.
Microwave ovens may operate on the same frequency as your telephone. You may experience static on your telephone while the microwave oven is operating. Do not install your cordless telephone in the same outlet or near the microwave oven.
Disconnect the telephone base from the modular jack and plug in a corded telephone. If calls are still not clear, the problem is probably in the wiring or local service. Contact your local service company (charges may apply).
If your phone shares a power outlet with a modem, or if it is plugged into a shared surged protector, try plugging in the phone (or modem/surge protector) at a different location. If this solves the problem, relocate your phone and modem farther apart from each other, or use separate surge protectors.
The layout of your home or office may be limiting the operating range. Try moving the base to another location, preferably a higher location for better reception. If your telephone base has an adjustable antenna, ensure it is pointing up.

• 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.
