One Talk desk phones utilize Voice over Internet Protocol (VoIP) technology, and require a broadband internet connection to connect to the Verizon mobile network.
The amount of broadband bandwidth and speed required is directly related to the quantity, type of desk phones and other devices sharing the broadband internet service.
Yes, you can use existing mobile or landline number as your One Talk phone number.

A connected desk phone is a 4G LTE device with an embedded eSIM that allows the device to work over the 4G LTE Network.
The screen and functions are intuitive and offer a user experience similar to an Android smartphone.
Setup is easy because it requires no network wiring and the device has a built-in embedded SIM (eSIM) card for connecting to the Verizon 4G / Voice over LTE (VoLTE) network.
For more information see our T67LTE and T64LTE Desk Phone pages.
No. Network Extenders funnel traffic over a broadband connection, potentially impacting the service quality of calls.
Since this is an eSIM based device, does the profile for the device get downloaded during activation?
No. The Verizon profile is preloaded into the device and can't be deleted or overwritten.
No. The device requires a power adapter to provide power to it.
A LTE desk phone informs the user the connection in use is no longer detected and prompts the user to switch over to another method. The phone needs to reboot to re-register over the selected network method (IMS for LTE or SIP for LAN).
With normal use, the phone will not consume more than 100 MB of data per month. The data allocation is set to the 500 MB ceiling and if the user goes beyond that, standard overage charges will apply. Users will receive an email in the rare event they approach 75% utilization and at any point in time the SPOC can see the data usage of the user in My Business.
Features like BFL, Directory download, and any My Biz transactions (change 911 address, remote reboot, remove end point, etc.) consume data.
Features like BFL, Directory download, and any My Biz transactions (change 911 address, remote reboot, remove end point, etc.).
Will Firmware and Configuration file downloads consume data from the 500 MB data allocation of LTE desk phone price plans?
No. Device related updates (module updates, device updates, configfile updates, etc.) will not use the allocated data plan.
The Ethernet port isn't functional when in LTE mode. It is only functional when the device is operating in LAN mode.
All One Talk features work, except:
- Multicast paging
- Line bridging
- Adding a native smartphone to share the number
- MMS messaging (regular SMS functions)
Press and hold the * key to bring up the option to reboot the device.
The T67LTE model can be used as a Red Phone, for specific purposes such as emergency communications (Special backgrounds, Red Handset and WPS Support). The T64LTE can't be used as a Red Phone.
The Expansion Module can only be used with the T67LTE.

Similar to Verizon HD Voice, a One Talk call will drop if you leave Verizon's 4G LTE coverage, unless the device is enabled for Wi-Fi Calling and a Wi-Fi network is available.
When outside of 4G LTE network coverage, the One Talk Mobile app will revert to the dialer of the mobile smartphone to make and receive calls. Only the advanced business features will be unavailable at that time.
Call-Through for the One Talk Smartphone Mobile app routes calls over the cellular network voice channel instead of the data channel. There is not an additional charge for this One Talk feature.
- Improved call quality
- Calls are routed over voice channel (not VoIP over public Internet)
- Multi-carrier support - Verizon phones use VoLTE, One Talk app on other carrier devices use that carrier's voice channel
- Uses voice minutes vs. using data against your smartphone plan for calls.
- Reduce costs and impact to user data plans (especially employee-owned devices - BYOD)
For more information on Call Through installation and usage, refer to our One Talk Features or First Steps pages.
When I'm using One Talk, what can I do to avoid dropped calls if I'm in a weak 4G LTE coverage area?
One Talk works best when you're in 4G LTE coverage. The calling behavior will fluctuate once you move outside of 4G LTE territory. If possible, connect to a Wi-Fi network when you're not in a strong 4G LTE coverage area.
Using the Transfer to Cell Phone option for call transfer will allow you to transfer the call from the app to your smartphone, which may provide a better calling experience when you have weak cellular signal.
Using the Call Through feature will provide you with the best overall experience for making, receiving and managing calls especially when experiencing a weak cellular signal.
One Talk activation varies depending on the device.
- If activating the service on an existing supported smartphone, the added functionality will be available within minutes of adding the feature to your account.
- For desk phones with a new line of service, you'll typically receive your device in 48 hours. Once you connect in to an Ethernet port, the desk phone will go through a zero-touch provisioning process (which could take up to 10 minutes). The phone will register, and any new software updates will be downloaded. Once completed, the device will be ready to make and receive calls.
- For the One Talk mobile app, once the new number (or ported number) is provisioned, the user must download the app and request an authentication PIN through the app. The PIN grants access to that particular device/app combination to register and obtain service.
If an existing telephone number is being ported from another carrier, the transition can take 10+ business days if porting from a landline carrier and 24-48 hours if porting from a wireless carrier. To ensure that you don't experience any service outage during that period, please do not contact your previous service provider to make any changes on the account until the porting is complete.
One Talk smartphone users can add One Talk Visual Voicemail, One Talk Premium Visual Voicemail and One Talk Voicemail to Text. One Talk smartphone subscribers may also utilize One Talk Basic Voicemail.
- To access One Talk Basic Voicemail, Call *86
- To access One Talk Visual Voicemail, use the Visual Voicemail app on the device or select the Voicemail icon in the phone dialer screen
For more information on accessing One Talk Basic Voicemail, Visual Voicemail or One Talk Voicemail to Text, see our Visual Voicemail FAQs.

No, One Talk requires new desk phones from Verizon that have built-in functionality and services for security and easy installation.
You can add the One Talk service to any iOS (version 12 or newer) or Android (7.0 Nougat or newer) smartphone or tablet, including those purchased through a service provider other than Verizon.
If your employee has a personal phone with service through a provider other than Verizon, that phone could still be eligible for One Talk. If eligible, the One Talk mobile app must be installed on that device, and the user will have 2 phone numbers - his/her personal phone number and a second One Talk phone number.
One Talk desk phones will be available through many of our business partners and a wide range of partners:
- In My Business
- Your Business Sales Representative
- Verizon stores
- Sales Representative: (800) 256-4646
There are numerous Bluetooth®, wireless and wired desk-phone headsets supported by One Talk. For a complete list of compatible headsets, see our One Talk Supported Headsets page.

Service billing appears as two individual line items: a service feature order, labeled "One Talk Service" and a second line item labeled, "Price plan type" or "Line Access Charge".
Your selection determines the type of charge that appears on the bill. Both options reflect the current service pricing.

Your selection determines the type of charge that appears on the bill. Both options reflect the current service pricing.
All One Talk voice minutes and usage are tracked for reporting purposes on your bill, regardless of the device used. This lets you review the calls you've made during your billing cycle, but it doesn't mean you pay extra for your calls.
The way your calls are billed varies by device:
- All plans available for One Talk come with unlimited minutes and text.
- Video calls use data for the video portion of the calls, which will apply against the allowance on your data plan, unless the device is connected to Wi-Fi.
- Calls placed from a One Talk desk phone use a broadband internet connection to the Verizon network. These calls don’t use your plan minutes, if applicable. They use data from your internet service provider (ISP), which is included in your monthly broadband service charges.
- Calls placed from the One Talk mobile app on a smartphone or tablet use data instead of minutes. These calls will apply against the allowance on your data plan, unless the device is connected to a Wi-Fi network.

Can I still make or receive One Talk voice calls if the Mobile Data setting is turned off on my device?
Yes. The One Talk Dialer can still make and receive voice calls using the One Talk service without data. The One Talk Mobile app requires data, and Wi-Fi can be used a substitute for mobile data. However, you won't be able to make video calls, because they use the data connection.
A One Talk voice call uses approximately .5 MB per minute.

Yes. One Talk works with the current 4G SIM card on your mobile device.
No. One Talk desk phones require an Ethernet connection to plug in the Cat 5 or Cat 6 cable that is provided with the phone. An analog telephone jack cannot be used. These jacks and cables connect to the data router in your business and aren't your typical phone service jack. The Ethernet cable will easily plug in to the correct jack and won't easily plug into an analog telephone jack.
If there's only one Ethernet (internet) connection where you plan to place the desk phone, then the internet line can be shared. Connect the cable from the router/modem splitter to the internet port on the back of the desk phone. Using another internet cable, connect the cable to the LAN jack on the computer, and the other end of the internet cable to the PC port on the desk phone.
What are the ports and protocols required to allow the desk phone and mobile clients to properly authenticate and receive service; and what are the default DSCP Marking Settings?
One Talk requires the following protocols and ports so that the devices have service and full functionality:
