Troubleshooting Common Issues

If people say your office called them when it didn't, your number is most likely being spoofed: scammers can put any number on caller ID, and these calls never go through your phone system. It usually stops on its own. Meanwhile, add a short greeting message, report it to the FCC, and contact VentureTel support.

A spam label doesn't necessarily mean your business did anything wrong. Long-owned numbers can still be flagged based on recent activity and feedback, and outside caller ID spoofing can contribute. STIR/SHAKEN authenticates genuine calls but isn't a spam-free guarantee, and caller name (CNAM) is separate from reputation. Send VentureTel support a call example, use expected calling practices, and register or request review with the screening services that apply.

Yealink T54W IP phones running older firmware 96.84.x.x cannot upgrade directly to newer 96.86.x.x firmware releases. An intermediate firmware upgrade to 96.86.0.18 is required due to changes in flash partitions, bootloader components, and internal signature validation. This intermediate upgrade can be performed via the web interface, provisioning server, or USB recovery method. After installing 96.86.0.18, the phone can be safely upgraded to any newer 96.86.x.x firmware version.

Rebooting your VoIP phone can often resolve minor issues such as no dial tone, poor call quality, and dropped calls. To reboot, disconnect the power source, wait 30 seconds, and then reconnect it, allowing the phone to fully power on and re-register with the service. This simple step can fix many common problems quickly and easily. If issues persist after rebooting, contact VentureTel support for further assistance.

To change the text input on a Yealink phone from letters to numbers, press the soft key below the current input type on the screen. This will cycle through the available input modes, including lowercase letters, uppercase letters, mixed input mode, and numbers only. Stop when the numbers only mode, indicated by 123, is selected, and then enter your password using the keypad. This should resolve the issue of the phone typing letters instead of numbers.
