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.

Tip 1 of 4
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 4
Static, noise, calls cutting in and out and other erratic performance may be caused by nearby electronic equipment and other cordless devices using the same frequency. In addition, police scanners and HAM radios can generate interference. Separate your telephone system from these devices as much as possible. -
Tip 3 of 4
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. -
Tip 4 of 4
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.

If your cordless headset base shares a power outlet with a modem, or if it is plugged in to a shared surge protector, try plugging the base (or modem/surge protector) in at a different location. If this solves the problem, re-locate your headset base or modem farther apart from one another, or use separate surge protectors. -

Tip 1 of 4
Confirm proper installation of the headset base power supply and headset battery. You should only use the power supply provided with your cordless headset. Make sure the electrical outlet is working and not controlled by a wall switch. -
Tip 2 of 4
When placing the headset in the charger, confirm that the charge contacts are making a good connection. The ON/OFF light illuminates on the headset while it charges.

Despite your VoIP box shows full signal strength, there could still be no dial tone/ display Line in Use/ etc. This may due to the abnormality of signal and voltage levels. Follow this short video to reset your VoIP box and its connected devices.

• 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]
