Frequently asked questions about caller ID

While on a call, you can make it a conference call by clicking the Add Call button in the in-call controls. Search for the person's name or dial their 10-digit number. While the second call is placed, the first call is on hold. Click the Merge icon to join all three parties together.

You can have at most a 3-party call. If you need to make it a larger call, click the Meet button and make it a Zoom meeting. You can invite additional participants as you normally do in a Zoom meeting. (Participants who don't have Zoom can use the dial-in number.)

While in a call, you can:

Access in-call controls like Hold, Mute, Add a Call, Meet, Transfer and much more.
Start a Zoom Meeting with the other person on the call.
Use Hold to call flip—switch the device you are using for the call (e.g., change from desktop app to cell phone app, or vice versa).
Call history - after each call, you can see your call history for inbound and outbound.  You can also listen to your voicemails from the Zoom App or Desktop.

Place or receive phone calls with the Zoom App on your desktop, laptop, smartphone or tablet.

In the App - be sure to use your Fresno State Zoom account.  If unsure, it is recommended that you click Sign Out, and Log in to and sign in using Signle Sign On (SSO) option.

After setup, you can start making and receiving calls using Zoom Phone on your device.

Making a call - use the dial pad to search through the directory in Zoom by typing the name of the person.  If they have a Zoom phone, their name and phone number will appear after the first three letters are typed in.   Once their name appears, their profile picture will display a small icon showing their status (On a call, in a Meeting, Away, etc.).

When placing calls outside of the campus, within the US and Canada, dial the 10-digit number if outside the 559 area code.  Dialing a 7 for an external call is no longer necessary.  

Use the in-call control button with the phone-to-phone icon (Transfer) to transfer calls. You have three options when transferring calls in the Zoom app. (If you have a telephone handset, see its documentation for its capabilities.)

  • Warm Transfer: Places your call on hold while you complete the transfer. This option is useful if you need to navigate an automated answering machine for the caller or if you want to speak to the receiving party before your call is transferred.
  • Blind Transfer: Transfers the call to the number and immediately hangs up your call. If there are any phone menu prompts, the other party will have to complete them.
  • Transfer to Voicemail: Transfers the call to the voicemail of a specified phone number. This transfer method might not work for all numbers. You can also transfer to voicemail by using DTMF codes (keypad codes using *).
    Be aware: When transferring a call, the caller ID displayed to the party receiving the transfer depends on whether they're an internal or external number.

If you chose the voicemail option in Settings, Zoom Phone forwards all unanswered and declined inbound calls to your voicemail. You can use the Zoom desktop or mobile app or the web portal to play and manage your voicemail messages.

You will also receive an email with an attached .mp3 file. If you delete the email, the voicemail will still be in the Zoom app. If you delete the voicemail in the Zoom app and have not directly deleted the email, you will still have the message in your email.

The Zoom app, web portal, and email will also provide a transcription of the message.

Option #1 - Install the Zoom app on your mobile device.

This will allow you to make and receive phone calls and SMS messages

using your campus number without needing to adjust any forwarding settings.

Option #2 - Adjust the Call Handling settings within your Zoom Phone account.
