It sounds like you have an idea of what opportunities are interesting to you. Refine that some more and come up with a copy paste response for recruiters. If they do not reply with useful information, then just end the conversation. Most recruiters are terrible at their job, the ones that aren't will engage you meaningfully.

Also, yes many will try to engage you on the phone and there's not really any way around that if you're starting a relationship with them. They need to get a feel for you before they can submit you to clients and phone screens are just an efficient means to do so.
