Phone Number Setup
Every agent needs a phone number before it can take calls. OnCallClerk provides a searchable inventory of US phone numbers you can assign in a few clicks.
Selecting a number
Open Agent Setup → Phone Number tab. Choose United States from the country dropdown, then optionally narrow the list with the filters below.
| Filter | What it does |
|---|---|
| Number prefix | Shows only numbers containing a specific digit sequence (e.g. "555") |
| Area code | Restricts results to a three-digit area code (e.g. "212" for New York) |
The system displays 10 numbers at a time. Each row shows the formatted number, city/state, type (Local or Toll-free), and a Select button. Use Previous / Next to page through results.
Match your local area code for a neighborhood feel, or look for repeating digits that are easy to remember.
Assigning the number
Click Select on the number you want. A confirmation modal shows the full details, review them and click Assign Number. The assignment is instant; your agent can start receiving calls right away.
An active subscription is required, and each agent can hold only one number at a time.
Viewing your current number
After assignment, the Phone Number tab displays a green "Active" banner with your assigned number. If no number is assigned you'll see a yellow warning instead.
Changing your number
Browse and select a new number the same way. The confirmation modal will warn that the switch replaces your current number. Click Replace Number to confirm.
Your previous number is released immediately and cannot be recovered. Any marketing materials or business listings referencing the old number should be updated.
Call escalation
When a caller asks for a human or the AI decides the query needs one, the call is forwarded to your Escalation Phone Number.
Set this under Agent Setup → Call Rules tab. Enter the destination number and click Save Changes. The agent will use this number whenever it triggers a transfer.
Troubleshooting
"Subscription Required" error, You need an active plan before assigning a number. Visit Subscription in the sidebar.
No numbers in search results, Try a different area code or clear the prefix filter. Some area codes have limited inventory.
Assignment failed, Confirm your subscription is active, then try a different number. Contact support if the issue persists.
Agent not receiving calls, Check that the number shows as "Active" in the Phone Number tab, your agent status is set to active, and your subscription is current.
