How Call ViVi Connects to Your Phone System

Call ViVi works with most of phone systems supporting small businesses. She uses one of three simple connection methods. There’s no “right” answer, just the option that fits your business best.

Common Phone Systems We Work With

  • Google Voice/Google Workspace Voice

    Use call forwarding for a fast start, or port your number for full voice + SMS support.

  • AT&T
    Forward calls immediately or port your number when you’re ready to consolidate.

  • RingCentral
    Vivi works alongside RingCentral using forwarding or Bring Your Own Carrier (BYOC) configurations.

  • Other VoIP & SIP providers
    If your system supports call forwarding or SIP, ViVi can usually connect in a few easy steps.

Call Vivi is compatible with most major phone providers, including:

If you’re unsure about your setup, our team can help you choose the best option.

🔄 Option 1: Call Forwarding (Fastest to Start)

Best for:

Solo practitioners, small businesses, or anyone who wants to try ViVi quickly.

You keep your existing phone provider and forward incoming calls to your Call Vivi number. ViVi answers the call just like a front desk receptionist.

  • Your original number stays active

  • Calls are forwarded to ViVi

  • No porting or carrier changes

  • You can turn it on or off anytime

What this looks like:

Good to know:

Call forwarding works for voice calls only. Text messages stay with your original provider.

🔁 Option 2: Number Porting (Cleanest Long-Term Setup)

Best for:

Businesses that want one number for calls and texting, or plan to use ViVi long-term.

You move, or “port”, your existing phone number into your own Twilio account, then connect it to Call ViVi. From that point on, ViVi answers calls. Your team continues to send and receive texts from the same number.

  • One business number

  • Calls answered by ViVi

  • Texting enabled (after approval)

  • You control your phone number directly

What this looks like:

Good to know:

Porting usually takes 3-10 business days, and your number keeps working during the process.

🔌 Option 3: Bring Your Own Carrier (BYOC)

Best for:

Practices with internal IT, higher call volume, or compliance requirements.

You connect Call Vivi to your existing phone carrier (such as Twilio, SIP, or a VoIP system). ViVi becomes your AI receptionist while you keep full control over your telecom setup and billing.

  • You own your phone infrastructure

  • Twilio (or your carrier) bills usage directly

  • Call ViVi provides the AI agent and workflows

  • Ideal for HIPAA-ready environments
