Welcome to the RingCentral Community

This kind of setup would be too complicated for a single user. It is much better to create another one and assign the other phone to it.

I was thinking this as well. I've set up a new account for the second desk. How can I get both to ring when this user is called directly?

Edit:

Sorry, when I say "called directly" I mean a non-call queue call.

Thanks, but this forwards all calls (including queue calls). Is there a way to only forward direct calls?

You may create a custom rule. You can enter the direct number under "Called Number". Check on this KB article, https://support.ringcentral.com/article/How-to-access-the-advanced-call-handling-feature.html
