Unofficial Checklist now that Telephony is live

  1. Go to The UCSB Identity Manager and make sure your primary email is of the form While departmental aliases such as CoE emails point to the same Connect account, zoom sometimes does not recognize the aliases as aliases and instead treats them as different accounts. You do not want to be locked out of your zoom because it is only allowing in your alias when SSO requires This needs to be done as soon as possible since extension allocation can be done a full month before the actual migration.

  2. Go to the UCSB zoom page and make sure your primary email there is also listed as Please also set your time zone to pacific time.

  3. Make sure you have the full zoom client installed on your computer and delete any other copy you might have. Zoom has an annoying habit of downloading copies to your browser cache if you open a zoom link and don’t click “open app”. The browser version is not a full version and can interfere with telephony. If you have a Jamf managed computer, congrats this step is already done.

  4. Follow the instructions for Emergency Address Setup above for your OS, either Mac or PC. If you have a Jamf managed computer, the location services package should already be installed. Please note the emergency location is TWO lines and you need both.

  5. If you are not using a physical phone, the zoom app needs to be open, with a usable camera and mic, to use all features. Zoom might also need permission for “accessibility” and “screen recording” under system preferences >> security & privacy if you are using a Mac device. Camera and Microphone recommendations are listed in this Knowledge Base

Additional Unofficial Checklist for Physical Telephony Phones

  1. For those getting additional physical phones, be sure to contact your local IT organization before ordering your phones.

  2. Telephony phones cannot be used in many labs and other areas deemed “LIFE SAFETY” as they require both power and internet to run. Copper land line phones do not need internet and can be powered through their copper lines in case of an emergency.

  3. Phones need to be connected to an active Ethernet port. Not all ports are active and it can take comm services up to a month to activate ports if the port you want to use is not wired up.

  4. Phones need to be registered via their hardware MAC address to get an IP address. That should be on the outside of the box the phones come in. Please see

  5. Phones come disassembled, ECI is NOT responsible for assembling your phone. Please follow the assembly instructions. Ethernet, Phone, and Headset ports are different ports.

  6. If your time is not correct, you will not get dial tone. Set your timezone by going to the home button (House Icon)

    1. Select Settings > Basic > Preferences > Time & Date.

    2. Select from Clock Date, Clock Time, Clock Order, Timezone or Enable/Disable.

    3. Scroll through the options under each of these selections using the Up and Down arrow keys.

    4. If you did not set your timezone via zoom, it will default to Greenwich Mean time and your phone will not work. Click Pacific Standard Time (number key 5 if you are using most models)

    5. Press the home menu again

    6. go to Settings >> Basic >> update configuration, to apply the changes above.
