Hi Rhobie Ann,
As a follow up on the information Luiggi provided, I had a look at the request you received and would like to strongly advise you to disregard it. Please note that all conversations before a contract is started must be through Upwork Messages, where you can send messages and have voice/video calls with clients. Please see this article for more information about sharing of contact and other information.
As a new freelancer on Upwork, I'd strongly suggest reviewing the resources we shared here and here. Feel free to follow up here if you have any questions or need advice!
Thanks for this great update. The users were finding issues with the video or voice call quality. Thanks, you noticed and improved it further.
Looking forward to testing it.
