How numbers fit into Fluents.ai
Numbers sit between your customers and your agents:-
For inbound calls:
Customers dial a number → Fluents.ai receives the call → your inbound agent answers. -
For outbound campaigns:
Your campaign uses one or more numbers to call a list of contacts → the caller ID they see is the number you chose.
- Own numbers fully inside Fluents.ai (when you buy numbers)
- Reuse numbers you already have with external providers (when you link numbers)
- Organize numbers with tags so you can easily assign the right ones to agents and campaigns
Numbers list view
In the Numbers section, you’ll see all phone numbers available for your account. Typical columns include:- ID – Internal identifier for the number.
- Number – The phone number itself.
- Agent – The inbound agent currently assigned to this number (if any).
- Telephony provider – For example, Fluents, Telnyx, or Twilio.
- Account connection – Which provider account the number belongs to (when applicable).
- Tags – Any tags you’ve added to group this number (for example,
sales-us,after-hours).
- Search numbers – Quickly find a specific number by searching its digits.
- Filter by tags – Show only numbers that match one or more tags.
Buying vs. linking numbers
Fluents.ai supports two main ways to add numbers to your account.1. Buying numbers in Fluents.ai (US only)
Use this when you do not have your own telephony provider and want Fluents.ai to handle the phone line for you.- Currently, you can buy US phone numbers directly in Fluents.ai.
- Click New in the Numbers page.
- Choose the Fluents provider (or built‑in option, depending on your UI).
- Pick an available US number.
- Add the number to your account.
- Optionally assign an inbound agent and tags as part of the setup.
- Setting up dedicated inbound lines (for example, Support, After‑hours, Sales).
- Having clean caller IDs for outbound campaigns.
- Getting started quickly without creating accounts at external providers.
2. Linking existing numbers you already own
If you already have phone numbers with a telephony provider (for example, Telnyx or Twilio), you can link those numbers to Fluents.ai. Linking is simple:- In the Numbers page, use Link Existing (or the equivalent action).
- Enter the phone number you want to link.
- Fluents.ai validates and, if everything looks good, adds that number to your list.
- Optionally assign an inbound agent and tags when you link it.
- Teams who already use Telnyx, Twilio, or another provider and don’t want to change numbers.
- Preserving existing phone numbers that customers already know.
- Gradually migrating from manual or legacy phone workflows to AI agents.
Assigning numbers to agents (inbound)
To receive inbound calls, a number must be linked to an inbound agent. Conceptually:- Number = the phone line customers dial.
- Agent = what answers the phone and handles the conversation.
- Main business line → reception or routing agent.
- After‑hours line → after‑hours agent.
- Support line → support triage agent.
- Set the Inbound Agent for that number.
- Change the assignment later if your workflows change.
- One number to one inbound agent.
- Multiple numbers to the same agent (for example, regional numbers that all route to the same agent).
Using numbers in campaigns (outbound)
For outbound campaigns, numbers are used as the caller ID your contacts see. You can:- Choose which specific number (or pool of numbers) a campaign should use.
- Use different numbers for different regions, brands, or purposes.
- Reuse the same number across multiple campaigns when appropriate.
Organizing numbers with tags
Tags let you group and filter numbers so you can easily assign the right ones to agents and campaigns. Examples of tags:inbound-supportafter-hourssales-ussales-euclinic-a,clinic-b(for multi‑location businesses)
- When creating a campaign, you can choose numbers by tag (for example, use all
sales-usnumbers). - In the Numbers page, you can filter by tag to see subsets of numbers (for example, all after‑hours lines).
- When assigning numbers to inbound agents, tags can help you find the right set quickly.
Typical number strategies
Here are a few simple patterns that work well:Inbound after‑hours agent
- Buy or link a dedicated after‑hours number.
- Tag it
after-hours. - Assign it to your after‑hours inbound agent.
- Optionally use the same tag when filtering or reporting.
Outbound sales campaign
- Buy or link several local numbers for a region (for example, US East).
- Tag them
sales-us. - In your outbound sales campaign, choose numbers with the
sales-ustag. - Your contacts see a familiar local caller ID, while the campaign manages pacing and retries.
