Which sip client has unobtrusive incoming call notifications?

Question

SIP

Hello.
I am looking for a sip client for windows that would have unobtrusive notifications of incoming calls. For example, to show a pop-up window next to the clock, as messengers do. Or something else, but not in the center of the screen and without intercepting control from the current active window.
