This article lists common questions and suggested troubleshooting for Zoom Phone.
This article covers:
If the Phone tab shows on some devices and not others (for example, showing on your mobile phone while on data but not on their computer), it is likely an issue with the application version or a network/firewall issue.
If the Phone tab is not showing on the desktop client or mobile app, it is likely an issue with the account. Contact your admin and they can assign an extension. You can also try signing out and back in to the client or app.
This is likely a network issue. Try placing a phone call on a different network connection or from a mobile device using data. If other networks do not drop calls, check the firewall/ports of the network that is dropping the calls. Learn more about Zoom Phone error codes and suggested troubleshooting.
Unfortunately, you can't recover a voicemail that's been deleted. If your admin enabled voicemail transcription, you will receive an email notification with the voicemail transcript. You can still access this email to read the voicemail. You can also download an MP3 file of your voicemail for safe keeping.
Unfortunately, you can't recover a call recording that's been deleted. If your admin enabled call recording transcription, you will not receive an email notification with the recording transcript. You can also download an MP3 file of your call recording for safe keeping.
Try signing out of the Zoom desktop client or mobile app, then sign back in. If you don't see the SMS tab, contact your admin. They may have to enabled SMS for you.
Please check the error codes article. Note that the error code is the last 3 digits of the code you see in the error notification.
