Zoom Phone
Half the price, and your team already knows it
At around $10.50 per user it is the cheapest credible option, and if your company already runs Zoom for meetings, the phone system becomes a tab in software everyone opens anyway. It covers the essentials properly: auto-receptionist, call routing, texting.
What you give up: Fewer integrations and thinner analytics. If you need call reporting beyond the basics, or a deep CRM connection, you will notice what is missing.
