This makes business phone systems a perfect solution for remote teams and professionals who travel frequently.

• You want your phone system to integrate with other apps and tools: Great virtual phone providers integrate with tools like Microsoft 365, Canvas, Salesforce, and Zendesk. These integrations enable seamless communication and follow-ups with clients.
