How Voice Channels Work
Voice channels connect your AI agents to phone numbers. When someone calls the number (or you initiate an outbound call), your agent handles the conversation in real-time.
Call Flow
Create a Voice Channel
- a
Navigate to Channels in the sidebar.
- b
Click + New Channel.
- c
Select Voice as the channel type.
- d
Enter a name for your channel (e.g., "Main Support Line").
Get a Phone Number
You have two options for getting a phone number:
Provision New Number
Get a new phone number directly through Nutalk. Fastest option.
- • Choose country and area code
- • Number is ready instantly
- • Monthly fee applies
Bring Your Own Number
Port an existing phone number you already own.
- • Submit number porting request
- • Verification required
- • Takes 1-2 business days
Provisioning a New Number
- a
Select Provision New Number.
- b
Choose a country (US, UK, Canada, etc.).
