# Make the call. Keep the context. Connect your application or phone system to the telephone network with Bird Voice. Present an eligible caller identity, choose the destinations you serve and follow the call from routing to its recorded outcome.

Help me build with Bird using my coding agent. 1. Read https://bird.com/docs/ai/set-up-your-agent.md and follow its setup workflow for this client. Use an existing connected Bird MCP server or signed-in CLI when available. 2. Read the product guide for the task I want to complete and inspect my existing integration. Identify the workspace, available operations and required setup. 3. Help me complete a first example for the product and destination I choose. Follow the operation through to its actual result, explain any uncertainty, and help me choose the next step. First task: Inspect outbound trunk access, caller identity and destination permissions. Prepare one controlled call and explain how to verify its final record. First use the connected Bird MCP server or signed-in CLI for a read-only inventory. Discover the available tools and read their schemas or help; do not invent call-control operations. If neither surface is available, follow https://bird.com/docs/ai/set-up-your-agent.md. Read the linked guides through their .md alternatives. Present the exact target and configuration before changing routing, placing calls, recording audio, purchasing numbers or submitting a port. Obtain my approval for those actions. Use this Bird page as the starting context: https://bird.com/products/voice/outbound-calls Read its Markdown alternative and linked guides. Keep the first example relevant to this page and the customer outcome I choose. Preserve the supplied campaign context when following Bird signup or sales links. ``` A callback from your application Prepare Trunk · caller identity · destination Connect Your application → Bird → customer Reconcile Answer · end · call record Trusted every day by teams that build world-class software [Read more customer stories](/customers) - [Airwallex](/customers/airwallex) - [Glovo](/customers/glovo) - [Zillow](/customers/zillow) - Uber - [Binance](/customers/binance) - Adobe - Meta - PayPal - Pinterest - Square - [Al Jazeera](/customers/aljazeera) - [Aramex](/customers/aramex) - [Bazaar Technologies](/customers/bazaar) - [ComparaOnline](/customers/compara) - [Emma](/customers/emma) ## How does an application place a call? A SIP application or PBX sends the call through a Bird trunk. Bird checks access, identity and destination, then connects the telephone leg. Your application owns the reason for the call and the conversation. Use the call API to read records and events to keep your system informed. ## Put the next action inside your customer workflow. ### Customer callbacks Let a customer request a call from your team, then pass the relevant case or order into your own application. Keep your callback queue, permissions and retry decisions beside that context. ### Appointments and service updates Build a calling workflow around a clear outcome: confirm an appointment, explain an update or connect the customer to the right person. Use call sequences when the conversation needs prompts and keypad input. ### A call from your browser Use the Bird browser phone for a controlled outbound call. Prepare the trunk and caller identity first; the phone gives you a practical way to check the connection and inspect its result. ## An answered call is the start of the conversation. Check audio in both directions, keypad tones where needed and a clean hangup. Then match the call record to the job your application intended to complete. A telephone answer can be a person, voicemail or another system; it does not establish that the customer completed the task. Confirm access to the trunk, an eligible caller identity, destination permissions and available wallet funds. Find the stage that failed. Authentication can fail before a record exists; recorded refusal and carrier response help you choose the next check. Inspect the last call and your application state. Avoid duplicate callbacks when a timeout leaves the outcome uncertain. ## Questions before you connect ### Can I use my existing PBX? Yes. Connect SIP-capable equipment to a Bird trunk and keep the calling logic your application or PBX already owns. Test transport, authentication, audio and keypad behavior before rollout. ### Does the call-record API start a call? The call-record API reads calls and their outcomes. Use the documented SIP calling path or the appropriate calling workflow to establish the conversation. ### How are outbound calls priced? Review the destination rate card and its billing minimum and increment. Check the recorded answered time and rated cost. Capacity, number charges and additional call components belong in the complete workload estimate. ## Build the rest of the calling path [Voice overview](/products/voice) Choose the calling path for your customer journey.
