Ability to Detect if User is Already in a Call without initiating the call.

Here’s a concise version in one paragraph:

We would like to request a feature that allows us to check if a user is already in a call before trying to connect with them. Currently, the only way is to make a call and then handle the error if the user is busy, which is not efficient. A simple method like getUserCallStatus(userId) or isUserInCall(userId) would help us identify if the user is in a call without initiating one, making the experience smoother and avoiding unnecessary call attempts.
