Business Voicemail Greetings If I Want To Have 3 Businesses With 3 Phone Numbers & Voicemail Greetings, How Can I Do It With 1-2 Phones?

If I want to have 3 businesses with 3 phone numbers & voicemail greetings, how can I do it with 1-2 phones? - business voicemail greetings

I wonder about the possibilities to minimize the phones and phone lines, while only 3 phone numbers and separate greetings VM. I have only 1 line in my house + 1 cell phone. I do not want business calls from the line of the house. What options do I have? Carry 3 phones with me? Thank you!
