Voice numbers
Give your customers a number that reaches you.
Connect your business numbers to the way your team answers calls. Route an incoming call to a SIP trunk or a verified forwarding destination, and manage caller identity for the calls you place.

A number held in your Bird workspace can receive calls when its capabilities allow it. A number verified as a caller ID proves control for an outbound identity; its current carrier still handles incoming calls. Verifying a caller ID does not move the number or change where customers reach you.
Choose the number around the customer journey.
A number for your phone system
Connect an inbound-capable number to a trunk with delivery gateways. The number chooses the route; your PBX or application decides which person, queue or workflow answers.
A forwarding destination
Send the call onward to a verified number when that is the right answer for your team. Check the caller identity presented on the forwarded leg and account for both legs in the cost.
An existing business number
Inventory the number, country, type and current provider before planning a migration. Confirm eligibility and the porting process with Bird, then coordinate the number move with your application cutover.
Test the number as a customer would.
Call from the networks and locations that matter to your customers. Confirm that the intended team answers, the unanswered path is useful and the recorded route matches the configuration. A successful test from one phone is evidence about that path, not every network.
Availability
Review the current catalogue for the number type and market. Capability, registration requirements and price can differ by number.
Routing
Configure an answer before sharing the number. Keep a record of the previous route so a change can be reversed deliberately.
Identity
Use the eligible identity for the call and verify how it appears on representative receiving phones. Presentation depends on the receiving network too.
