I'd like to screen my phone calls

I have a co-manager who delights in calling me.

All the time.

She calls to tell me when she figures something out about work.

She calls to tell me when she leaves me notes at work (to make sure I know a note will be waiting for me)

She calls to tell me things I don't really need to know

She called me a few minutes ago and started a conversation about work, to which I said I'd talk to her when I got there (which is in an hour or so).

I wish she wouldn't call me
