Your business identity appears to customers while you work from the mobile app.
Basic simplicity · Plus collaboration · Advanced tools
Features that connect clearly to the service level you need.
Start with a separate business number and straightforward calling. Move to Plus for messaging and teamwork, or Advanced when more sophisticated call handling and productivity tools become useful.
The everyday experience
It still feels like using a phone. It just works like a business system.
Call from your business number, keep customer texts with the business, and use the same familiar tools without handing out your personal number.
Customer conversations and picture messages stay separate from personal messaging.
Desktop access and physical handsets can join the same setup without changing the core experience.

Professional calling
The foundation that separates the business from the personal phone while keeping work accessible.
Business messaging
Meet customers where they already communicate, using the business identity rather than a personal cell number.
Call handling and teamwork
Move beyond a single ringing phone when the business needs schedules, groups, or a more polished customer journey.
Productivity and specialized needs
Add these capabilities when they solve a specific operational or customer-service need.

Mobile and desktop access should not be the confusing part.
The Gemini Lines mobile and desktop experience, powered by ConnectUC, is the consistent starting point across all three public service levels.
Physical handsets remain an option—not a requirement.
