Tip: You can copy and paste phone numbers directly into the dial pad.
Receiving a Call

When someone calls your Zoom Phone number, a notification pops up. Click Accept to answer, Decline to send to voicemail, or Silence to stop ringing.

Incoming call options
Checking Voicemail

Click the Phone tab, then select the Voicemail tab. You'll see a list of all voicemail messages. Click any message to play it.

Checking voicemail steps
Setting Up Your Voicemail Greeting

Go to the Zoom web portal and navigate to Phone → Settings → Voicemail. You can record a greeting using your microphone, upload an audio file, or use the default system greeting.

Transferring a Call

During an active call, click the Transfer button. Search for a colleague by name or enter a phone number.

Warm transfer: You speak to the other person first before connecting them to the caller. Use this when you need to give context.

Blind transfer: The caller is sent directly to the other person. Use this for straightforward transfers.

Putting a Call on Hold

During an active call, click the Hold button in the in-call controls. The caller hears hold music. Click Resume when you're ready to continue.

Using the Company Directory

In the Phone tab, click Contacts or use the search bar. Type a colleague's name to find them. Click their name to see their number and click the phone icon to call them.

Forwarding Calls

To forward all calls to another number, go to Phone → Settings in the Zoom app. Toggle on Call Forwarding and enter the number you want calls sent to.

Do Not Disturb

Click your profile picture in the top-right corner and set your status to Do Not Disturb. All incoming calls go straight to voicemail. Click the status again to turn DND off.

Tip: DND applies to both desktop and mobile. If you turn it on in one place, it's on everywhere.

Allow Notifications & Permissions

Your phone will ask for several permissions:

  • Contacts: Optional — allows you to see your phone contacts inside Zoom.
Mobile-Specific Settings

Do Not Disturb: Tap your profile picture → Set status to Do Not Disturb.

Notifications not working? Check your phone's Settings and make sure Zoom has permission to send notifications.

Wi-Fi vs. cellular: Zoom Phone works on both. For best call quality, use Wi-Fi when possible.

FAQ & Troubleshooting

Common questions, troubleshooting steps, known issues, and how to get additional help.

Common Questions

What is my new Zoom Phone number?

Your Zoom Phone number was assigned when IT provisioned your account. You can find it in two places:

  1. Open the Zoom app and click or tap Phone in the sidebar.
  2. Your assigned number appears at the top of the Phone screen.

Alternatively, sign in to the Zoom web portal at zoom.us, go to Profile, and look for the Phone Number field.

If no number appears, your account provisioning may still be in progress. Check with IT — it typically completes within 24 hours of accepting your invite.
Can I keep my existing phone number (number porting)?

Number porting — transferring your current phone number to Zoom — may be possible depending on your carrier. This is handled by UTEC IT in coordination with Zoom support. The process typically takes 2–4 weeks.

If you need your existing number ported, contact IT Support with the following information:

  1. Current phone number
  2. Current carrier name
  3. Account holder name on the carrier account
Until porting is complete, your calls will go to your newly assigned Zoom Phone number.
How do I set up call forwarding?

Call forwarding is managed through the Zoom web portal:

  1. Go to zoom.us and sign in with your UTEC Google account.
  2. Click Phone in the left sidebar, then select Settings.
  3. Under Call Handling, find the Forward to option.
  4. Enter the number or extension you want calls forwarded to.
  5. Set the conditions (e.g., forward when busy, when unanswered, or always).
  6. Click Save.
You can also set your status to Do Not Disturb in the Zoom app to send all incoming calls straight to voicemail without setting up forwarding.
How do I set up or change my voicemail greeting?

Your voicemail greeting is managed in the Zoom web portal. You can record a custom greeting or upload an audio file:

  1. Sign in at zoom.us with your UTEC Google account.
  2. Click PhoneSettings.
  3. Scroll down to Greeting & Leave Voicemail Instruction.
  4. Click Edit next to the voicemail greeting.
  5. Choose Add Audio and either record directly in your browser or upload an MP3/WAV file.
  6. Save your changes.

See the Account Setup guide (slides 9–12) for annotated screenshots of this process.

How do I access my voicemail messages?
  1. Open the Zoom app and click or tap Phone.
  2. Select the Voicemail tab at the top.
  3. Click or tap any message to play it. A text transcript appears below the playback controls.
  4. To call back: tap the phone icon next to the message.
  5. To delete: swipe left on mobile, or right-click the message on desktop.
Voicemail transcripts are automatically generated by Zoom and may not be 100% accurate for technical terms or proper names.
Can I use Zoom Phone on my personal mobile device?

Yes. Install the Zoom Workplace app from the App Store (iPhone) or Google Play (Android), then sign in using SSO with your @utecinc.org Google account.

See the Mobile App Setup guide for step-by-step installation instructions for both iOS and Android.

Using Zoom Phone on a personal device uses your phone's data or Wi-Fi — there are no additional charges to your UTEC account for mobile use.
How do I transfer a call to another person?

During an active call, you have two transfer options:

  1. Click or tap the Transfer button in the in-call controls.
  2. A dialog will appear — search for a colleague by name or enter their number.
  3. Choose Warm Transfer (stay on the line until the other person picks up) or Blind Transfer (transfer immediately without waiting).
  4. Confirm the transfer.
You can also transfer directly to a voicemail box — useful if the recipient is unavailable and you don't want to ring their line.
What happens to my calls when I'm away or on Do Not Disturb?

Do Not Disturb: Set your status to DND in the Zoom app. All incoming calls will go directly to voicemail. Your status appears as a moon icon to other users.

Away: Setting your status to Away does not automatically forward calls — callers will still ring through. Use call forwarding or DND to control call routing when you're unavailable.

Offline / App closed: If the Zoom app is not running on any device, calls typically go to voicemail after a short ring period.

Can I make and receive calls from a web browser (no app)?

Yes, with limitations. Zoom Phone is accessible via browser at zoom.usPhone, but the full calling experience (including receiving inbound calls) requires the desktop or mobile app to be running.

For reliable call handling — especially receiving calls — it is strongly recommended to keep the Zoom desktop or mobile app installed and running.

How do I find a colleague's extension or direct number?
  1. Open the Zoom app and click or tap Phone.
  2. Select the Contacts tab.
  3. Search by name to find any UTEC employee with a Zoom Phone number.
  4. Click their name to call them directly.

You can also dial colleagues by their extension directly from the keypad — check with IT for the internal extension list.

Troubleshooting

No audio — caller can't hear me / I can't hear the caller
  1. Check that your microphone and speaker (or headset) are not muted at the system level.
  2. In the Zoom app, click your profile picture → SettingsAudio. Select the correct input and output devices.
  3. Ensure Zoom has microphone permission: on Mac, check System Settings → Privacy & Security → Microphone. On Windows, check Settings → Privacy → Microphone.
  4. Try ending and restarting the call.
  5. Restart the Zoom app and attempt the call again.
Can't sign in / "Invalid SSO domain" error
  1. When prompted for the company domain, enter exactly: utecinc (no spaces, no .org).
  2. Make sure you're signing in via SSO — not with an email/password or a personal Zoom account.
  3. Ensure you're using your @utecinc.org Google account, not a personal Gmail.
  4. Clear your browser cache and try again, or try a different browser.
  5. Sign out of all Zoom sessions at zoom.us/profile and sign back in.
Zoom app crashes or freezes
  1. Force-quit the Zoom app and reopen it.
  2. Check for updates: click your profile picture → Check for Updates. Install any available update.
  3. Restart your computer or mobile device.
  4. Uninstall and reinstall the Zoom app (your settings and call history are stored on Zoom's servers and will sync back).
  5. If crashes continue, note the time and contact IT — they can pull diagnostic logs.
Incoming calls not ringing on my device
  1. Check that your device volume is turned up and not on silent/vibrate-only.
  2. In the Zoom app, go to SettingsAudio and confirm your ringtone output device is correct.
  3. Make sure your status is not set to Do Not Disturb.
  4. Check Zoom's notification settings in your OS (Mac: System Settings → Notifications → Zoom; Windows: Settings → Notifications → Zoom).
  5. On mobile, ensure Zoom app notifications are enabled in your phone's notification settings.
  6. Make sure the Zoom app is not in a paused/background-restricted state on mobile.
Phone tab is missing in the Zoom app
  1. Confirm your account has been provisioned with a Zoom Phone license. Not all Zoom accounts include Phone — check with IT.
  2. Sign out of the Zoom app and sign back in using SSO (utecinc).
  3. Update to the latest version of the Zoom app.
  4. If still missing after the above steps, contact IT — your license may need to be re-assigned.
Poor call quality (echo, choppy audio, static)
  1. Check your internet connection — Zoom Phone requires a stable broadband connection (minimum 1 Mbps up/down for voice calls).
  2. Move closer to your Wi-Fi router, or connect via Ethernet if possible.
  3. Close other bandwidth-heavy applications (video streaming, large downloads).
  4. Try a different headset or audio device to rule out hardware issues.
  5. In Zoom Settings → Audio, disable Enable Original Sound if it's on, and ensure noise suppression is enabled.
