You could skip the asterisk solution, and use the grandstream PBX. The GUI is significantly cleaner (also with less features) but should be able to have voicemail, ring groups, call queues or "agents", custom dial rules, etc. It would save you a lot of money over a traditional phone system.
The PBX would run around 300-500$ depending on where and what you get, but amazon has one for 360$ here https://www.amazon.com/Grandstream-UCM6204-Innovative-PBX-Ports/dp/B01LZKCBD7/ref=sr_1_1?s=electronics&ie=UTF8&qid=1524428192&sr=1-1&keywords=grandstream+pbx
this pbx should be easy to setup (youtube videos are great on the subject) and the one price includes all features, and software updates are free as long as the device is still "supported".
As for your phone endpoints, grandstreams are cheap and work great. Their best phone IMO is around 100$ on amazon, and they have cheaper options as low as 50$ (on amazon)
grandstream GXP 2170 is pretty nice

Or the 1625 (for the cheaper option) for 40$ https://www.amazon.com/Grandstream-GXP1625-Medium-Business-Device/dp/B00VNMWRFK/ref=pd_sim_229_7?_encoding=UTF8&pd_rd_i=B00VNMWRFK&pd_rd_r=EJ27CJTWYAPA4D2Z7HNE&pd_rd_w=YQDrV&pd_rd_wg=3Cr2u&psc=1&refRID=EJ27CJTWYAPA4D2Z7HNE
The above phones will work with any sip based phone solution
If you're looking for the "easy drop in and just works" solution, you could try ring central, or 8x8. But i think theyre crazy expensive for what they actually do.
So grandstream phones are not "supported" by 3cx. There is no reason why they should not work though. Yealink is a budget brand that is supported. If you do not have poe at home you'll need to buy the power brick for them as well. (Grandstream phones come with the power brick)

In the 40 dollar range for grandstream I'd look at the 1625. HD audio, open vpn, backlight screen. It's a good worker phone.

Sorry I don't have any information about Yealink phones. =/
