Phone numbers are the entry point for inbound calls and the caller ID for outbound calls.

Numbers are provisioned instantly and usable as soon as the purchase completes.

Prerequisites

​
After Purchase

Once purchased:
  • The number is provisioned with your telephony carrier (Plivo by default for all regions including India; or your configured BYO SIP provider).
  • No agent is assigned by default. Calls to an unassigned number are rejected automatically.
  • You can add a nickname so the number is easier to recognize in Phone Numbers, agent selectors, batch call setup, and workflow call nodes.
  • You can assign an inbound agent version immediately. See Receive Inbound Calls.
  • You can use the number as the from_number for outbound API calls immediately. See Make Outbound Calls.

​
Verify the Number

To confirm the number is active:
  1. Open the Phone Numbers tab.
  2. Locate the number. The Status column should show Active.
  3. Click the number to open its detail view. The Telephony Provider field confirms which carrier is serving it.
Place a test inbound call to the number after purchase. With no agent assigned you will hear a rejection tone, which confirms the number is active and routing. Assign an agent version to start receiving calls.

​
Costs

Each number has a monthly rental fee shown during the purchase flow. This fee is charged per billing cycle regardless of call volume. Per-minute call charges apply separately based on your plan and telephony provider.
Monthly number fees are not prorated if you release a number mid-cycle. The full month is billed at the start of the cycle.

​
Release a Number

To release a number you no longer need:
  1. Open Phone Numbers.
  2. Click the number to open its detail view.
  3. Click Release Number and confirm.
The number is removed from your workspace, billing stops at the next cycle, and the number returns to carrier inventory.
Releasing a number is permanent. Inbound routing for that number stops immediately. Update any external systems or IVR configurations referencing the number before releasing.
