Phone Numbers
Dedicated phone numbers that connect voice and SMS to your AI assistants. Enable 24/7 automated communication, intelligent routing, and frictionless member signup via text.
What Phone Numbers Do
Phone numbers are your communication gateway:
- Two-way SMS with AI-powered responses
- Voice calls answered by AI assistants
- Work modes for business hours and forwarding
- Member signup via simple text message
- Unified history across all channels
Key Features
SMS + Voice in One Number
Each phone number supports both channels. Enable one or both based on your needs.
Member Signup via SMS
Let new members join by texting your number:
- They text a signup code
- Account created automatically
- Workflow starts immediately
Smart Forwarding
Route to humans when needed:
- Forward during off-hours
- Conditional forwarding based on caller
- Fallback when AI can't help
Agent Routing
Route inbound calls or SMS directly to an AI agent instead of a workflow. The agent responds autonomously using full conversation context, making it ideal for open-ended interactions that don't follow a fixed script. This works for both SMS and voice calls.
How It Works
Incoming Call/SMS → Route by Mode → AI or Forward → Logged
(your number) (hours/rules) (responds) (in chat)
When someone calls or texts your number, Gravity Rail routes the interaction based on your work mode settings—to AI, to a human, or an auto-reply.
