That's strange! I've not heard anything about this type of issue.
I might recommend creating a ticket with Support.

You can create a case HERE.

are you using RingCentral Phone desktop software (logo has a phone in it), if you log under one extension you can do that, however if you use the newer software (Logo has R in it ) you cant use this feature.

My company is also having this same issue, ringcentral doesnt seem to care. I am using both phone and desktop and its the same issue. i end up having to use my personal phone line which is not what we want.

Same problem here... can't speak to anyone.
