+1 for FoolishTech
I have a GV dedicated number for my business phone number, use it as such and have the phones forwarded to me, other techs or answering service depending on the time of day and what's going on. If it ever goes to voicemail it gets emailed to my ticketing system and everyone gets notified. I access all the business GV things using the online mobile version (

I also have a GV for my personal number. I have an Android phone and never give out my number to anyone. I only give out my GV number, only call from my GV and only text with my GV. I also add the GV number on my list of free call numbers so it's always free. The reason why I do this is because something can always happen to my phone either destroyed, reset, whatever. All my contacts are in Google Contacts attached to my GV account. So if I have to use another phone or my own phone after a reset, I just have to sign in with that Google account, download the GV app and all my contacts, texts, calls, etc. get put back on my phone automatically.
Reason why I chose GV as my actual business number is because it's not going anywhere, it doesn't cost anything and I can do whatever I need to do with it in the future. Reason for GV on the personal side: I can block people outright from calling or texting without involving my phone company (great for crazy dates), I get basically real-time online backup of all my calls/texts/contacts, with the ability to block I can give out my phone number freely to anyone who wants it without any downside.
And for the OP, both numbers were created completely new and announced like I got new service for both numbers.
