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.

When I talk on this phone, I hear an echo. Is there a way to reduce or eliminate this condition?
-
This unit employs state-of-the-art frequency hopping spread spectrum (FHSS) technology to achieve one of the longest ranges in the consumer cordless telephone industry. FHSS is a digital technology that is also found in cellular telephones. Just as it is common to experience echo in
some cellular telephone systems, some users will experience occassional echo while using this phone. The presence and/or level of echo will depend on the electrical characteristics of the connection between the phone and the users local central office. This is normal operation.
Try lowering the volume on your handset to reduce the echo.
My telephone handset appears to be dead. What should I do?
-
Tip 1 of 3
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. On average, this provides 5 hours of talk time and 6 days of standby. If the handset does not hold a charge or seems dead, we suggest the following:
• Please verify that the handset battery is securely plugged into the back of the handset.
• Check that there is power to the base and cradle. If there is power and the handset is placed face up, the CHARGE light on the base will be on.
• Place the handset in the cradle and charge it overnight, making sure that the dialpad is facing up.

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
To get better reception, try moving the telephone base to higher location. Relocate telephone base near a window if using telephone outside. -
Tip 4 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 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
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 7 of 8
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. -

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.

-
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.

NOTE: If you have caller ID service, the time will automatically be updated whenever caller ID information is delivered. However, since caller ID delivers the date, rather than the day, you must program the year once so the system can derive the day of the week.
To set the day and time, confirm that the answering system is turned on and then complete the following steps:
Step 1: Press TIME/SET. The system will announce the current setting.
Step 2: Press TIME/SET again. The system will announce the current day setting.
Step 3: Press CHANGE on the base until you hear the correct day.
Step 4: Press TIME/SET. The system will announce the current hour setting.
Step 5: Press CHANGE on the base until you hear the correct hour.
Step 6: Press TIME/SET. The system will announce the current minute setting.
Step 7: Press CHANGE on the base until you hear the correct minute.
NOTE: Pressing and holding the CHANGE button when setting the day and time will increase the minutes or years by 10.
Step 8: Press TIME/SET. The system will announce the current year setting.
Step 9: Press CHANGE on the base until you hear the correct year.
Step 10: Press TIME/SET to confirm. The system will announce the new day and time setting followed by a confirmation beep. -
Tip 5 of 5
First, deregister ALL handsets:
Step 1: Press and hold FIND HANDSET on the main telephone base for 10 seconds.
Step 2: When the IN USE light starts to flash, release the FIND HANDSET button.
Step 3: Press and release FIND HANDSET again. The IN USE light will turn off and in a few seconds, all handsets will be de-registered.
Step 4: All handsets will show NOT REGISTERED.
Now, register all handsets (1 handset at a time):
Step 1: Place the handset in the base unit or a charger that is connected to a power outlet. If PRESS FIND HNDST 4 SEC ON BASE does not appear on the screen after a few seconds, lift up handset and place in base or charger again.
Step 2: On the telephone base, press and hold FIND HANDSET for four seconds. Release FIND HANDSET once the IN USE light comes on.
After a while the handset will emit a series of tones, the newly registered handset will be assigned the lowest extension number not previously assigned to another system handset (1-4) when successfully registered. Repeat Steps 1 and 2 if the handset does not successfully register to the telephone base within two minutes.
REPEAT THE REGISTRATION PROCEDURE FOR EACH SYSTEM HANDSET.

• 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.
