a) The Google status page only reports outages on Google services that have a contractual service level; for example, the various pieces of G Suite, which customers pay to use. The Google Voice row only reflects the G Suite version of Google Voice, and it has nothing whatsoever to do with the consumer OBiTALK device status.
b) This may or may not be an actual outage. Perversely, this stuff seems to happen on Friday afternoons, and getting anyone at Google to work on it is very difficult -- I've been there and done that on several past outages that were more severe than this, and I was able to work with their engineering staff, but given the COVID-19 situation, they are short-staffed and prioritizing keeping critical services running.
c) They will have absolutely no sympathy nor interest in the problem if it is being caused by attempted business use patterns, such as mass calling or outbound SMS to multiple customers, friends, students, etc, which will automatically block or suspend your use of the service. I doubt this is the case here, since you are posting inbound call issues. But, before reporting, you need to sign into the correct Gmail account that holds your Google Voice number, and go to the Google Voice inbox or settings page. If you are re-directed to a suspension message, then your service has been shut down for abuse. Otherwise, you're fine.

We'll need you to post from the same Gmail account that holds your Google Voice number, provide detailed symptoms, and give Google Voice engineering your permission to examine your account.
