Phone Numbers

Get phone numbers for your AI agent and manage how calls are routed.

What is the Phone Numbers Page?

This is where you purchase and manage the phone numbers that people call to reach your AI agent. Each number connects to BLEUM through Twilio and routes incoming calls to your published procedures. You can also create Line Groups to organize multiple numbers into named lines and control which procedures each line has access to.

Getting Your First Number

Click "Purchase Number"

Open the purchase panel from the Phone Numbers page.

Search by area code

Enter the area code you want (e.g., 212 for New York, 415 for San Francisco). Choose a number that matches your business location or target market.

Purchase and configure

Click to purchase the number. BLEUM automatically configures the webhook so calls route to your AI agent.

💡 Tip Choose a number with an area code your customers recognize. Local numbers build trust and increase answer rates.

Line Groups

Line Groups let you organize your phone numbers into named lines — for example "Sales", "Support", or "After Hours". Once you create groups, each procedure in your Flow Builder must be assigned to one or more groups, so the AI only offers relevant procedures to callers on that line.

💡 Single number? If you only have one number and no groups defined, all procedures are automatically available to all callers. You don't need to set up groups at all.
Create a group

Scroll to the Line Groups section on the Phone Numbers page. Type a name (e.g. "Sales") and click + Add Group.

Assign numbers

Check the phone numbers that belong to this group, then click Save. A number can belong to multiple groups.

Assign procedures

Open any procedure in the Flow Builder. The Available on row in the header shows your groups as checkboxes. Select which groups this procedure should appear for.

In the Flow Builder list, published procedures are grouped by line. In the Call Journey rail, use the tab strip to preview each group's call experience and see which phone number callers will reach.

⚠️ Important Once you create at least one group, procedures are unassigned by default. You'll be warned if you try to publish a procedure with no group assigned, since callers won't be routed to it.

Common Questions

Phone number pricing is handled through Twilio. Standard US numbers are typically around $1.15/month. Call charges apply separately based on usage.

Number porting is handled through Twilio. Contact BLEUM support and we'll walk you through the process.

First, check that the number shows as "Active." If it's inactive, click "Auto-Configure" to reset the webhooks. Also verify that your server is running and accessible. Try calling the number yourself as a test.

Procedures assigned exclusively to that group become unassigned. They'll still exist but callers won't be routed to them until you assign them to another group.

Yes — check multiple groups in the "Available on" section when editing a procedure. It will appear under all selected groups in the Flow Builder list, and be available to callers on any of those lines.
