Verizon One Talk FAQs

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.

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.).

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.

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:

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.

The complete list of Feature Access Codes (FAC) (PDF*) is in the Feature tab in the One Talk portal.

There are 3 ways to access and manage your One Talk service number with your smartphone or tablet:

• One Talk Enhanced Dialer
• One Talk Native Dialer (iOS or Android)
• One Talk Second Number - Native Dialer on second SIM
• One Talk mobile app (iOS or Android)

The differences between the 3 depend on the smartphone carrier or device, how you set up features from the smartphone and access the features.

Yes. You can make a FaceTime call to any other FaceTime-capable device. It's not limited to One Talk user lines.

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.

There are a couple of ways to make a One Talk video call.

To place video calls on One Talk:

1. Enter the number on the Keypad tab (native or enhanced).
2. After connecting, tap the Video Camera icon.

If a call starts as a voice call, at any point during the conversation that call can be upgraded to a video call (as long as the other party has video calling capabilities on his/her device, denoted by an active Video icon on the phone display).

See iOS Native Dialer for available features.

To make a video call using Wi-Fi:

Make sure your device is connected using the Wi-Fi setting and not the 4G LTE connection.

You can make a One Talk Wi-Fi call (Voice and/or Video) the same way you would on any video calling-capable mobile device:

1. Enter a number with the phone dialer (native or enhanced).
2. Tap the Video Camera icon on the dialer.

A One Talk one-way voice/video call uses approximately 3.5 MB per minute.

A One Talk two-way voice/video call uses approximately 6.6 MB per minute.

Yes. You can switch a voice call to a video call anytime during the conversation using the One Talk mobile app and Enhanced Dialer.

The other party must have a video capable device and an active Video icon on their phone display.

Starting April 17, 2025, One Talk reporting & analytics requires enrollment to start collecting Call Detail Records (CDR) for reports. Customers that have accessed the site within the past 180 days prior to this date will be automatically enrolled and will not be impacted.

If at any time the business has not used the reporting and analytics service for 12 months, the business will be unenrolled, and call detail records will stop being collected.

Once enrolled for reporting and analytics, call detail records will start being collected for reporting. One Talk call detail records are not collected until the business has enrolled for reporting.

Once you have enrolled in reporting and analytics, your call records will start to be collected. It could take up to four hours to start seeing data in the reporting and analytics dashboard.

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.
