Place automated outbound calls that customers recognize and answer.

Trigger automated voice alerts, appointment confirmations, and customer callbacks from your application, or dial out from your existing PBX over a SIP trunk. Present verified local caller IDs so mobile networks connect your calls and customers pick up, then track ringing, answer timestamps, and billable talk time.

How do you place outbound calls from your app or phone system?

Start outbound calls from your backend with an API request that launches a published call sequence (or a personalized flow generated for that specific call) as soon as the recipient picks up. If your team runs a PBX, contact center, or SIP media server, connect it to a Bird SIP trunk to dial out using the same verified caller IDs and country controls.

Put automated alerts, callbacks, and click-to-call inside your workflow.

Customer callbacks and agent bridges

Let customers request a callback from your app or website instead of waiting on hold. Dial out from a local number in the recipient's country, play a spoken greeting or gather keypad input to confirm they are ready, and transfer the live call to your support queue or PBX.

Appointment confirmations and urgent alerts

Reach customers by phone when an appointment needs confirmation, a delivery arrives, or an account alert cannot wait in an email inbox. Pass customer names, times, and booking details into your call sequence so spoken prompts and keypad menus match the specific order.

Browser calling for support and testing

Place outbound calls straight from the Bird dashboard using the built-in browser phone without configuring a desktop softphone or sharing long-lived SIP credentials. Choose your caller ID, test carrier audio and keypad tones on a live number, and review the call record right away.

Deliver calls reliably and see why a call connected or failed.

Getting a phone to ring is just the start of an outbound workflow. Because voicemail or an automated system can answer, Bird tracks network call status separately from your sequence's keypad outcomes, sending real-time webhook events as calls ring, connect, and hang up so your app knows whether the customer completed the task.

Local caller IDs and spend guardrails

Present a local Bird number or a verified business caller ID so mobile carriers connect the call and customers recognize who is calling. Enable specific destination countries and set daily spend limits to block international toll fraud before a carrier is dialed.

Carrier and refusal diagnostics

See the exact stage where an unsuccessful call stopped. Call records separate pre-call policy refusals (such as an unverified caller ID, disabled destination country, or rate limit) from downstream carrier SIP responses like busy or unallocated numbers, with ringing time tracked separately from billable talk time.

Safe retries without double-dialing

Prevent network timeouts from triggering duplicate calls to the same customer. Supply an idempotency key when creating an API call so retries within the replay window return the original acceptance result instead of dialing a second time, and reconcile webhook updates against the call log.

Questions before you connect

Can I place outbound calls from my existing PBX or SIP server?
Yes. Connect your PBX, contact center, or SIP media server to a Bird SIP trunk over UDP, TCP, or encrypted TLS. You keep your existing dial plan and call routing while using Bird's carrier connectivity, verified caller IDs, and country-level spend controls.
How do I track whether a customer answered and completed the call flow?
Subscribe to voice webhooks to receive real-time events when a call is initiated, answered, and ended, including final SIP response codes and billable talk time. When running a published call sequence, inspect the sequence run trace in the dashboard or CLI to see which prompts played, which keypad digits the recipient pressed, and the exit reason.
Can AI agents or CLI workflows initiate outbound calls?
Backend applications and automated voice services can place calls directly through the HTTP API and Bird SDKs. When using the Bird CLI or MCP server in preview, an AI agent can prepare the outbound call request with its caller ID, recipient, and sequence data, then return a browser review link for a teammate to approve and run.
How are outbound calls priced?
Outbound calls are billed from your prepaid wallet by destination country. Billable time runs from answer to hangup, so unanswered ring time is not billed as talk time. Each destination rate defines its minimum billed duration and increment, and the rated cost appears on the call record.
