Why Forward Calls to Stack?​

Forwarding calls to your Stack phone number enables you to:

  • Leverage Voice AI: Enhance customer communication with AI-powered call handling and transcription.
  • Maintain Your Existing Number: Keep your current phone number visible to customers without needing to update it on marketing materials or directories.
  • Streamline Operations: Ensure all incoming calls are managed through your Stack account for better tracking and management.

How Call Forwarding Works​

When call forwarding is activated, incoming calls to your personal number (cell or landline) are automatically redirected to your Stack phone number. Stack then manages these calls using its advanced Voice AI capabilities.
