# Bird vs Telnyx for Voice Bird connects calling to your Bird workspace through SIP trunks, call sequences and shared operational records. Telnyx combines programmable calling with an AI assistant builder that configures models, voices and tools in its portal.

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: Read the relevant migration guide and inventory my current provider's numbers, call-control code, webhooks, recordings and speech-runtime dependencies. Prepare one complete migration test and a rollback plan. Keep the current service running until I approve cutover. 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/compare/bird-vs-telnyx 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. ``` 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) ## Which integration fits your calling workflow? Compare the job you need each platform to perform. A shared capability does not establish identical behavior, cost or audio quality. | Capability | Bird | Telnyx | | --- | --- | --- | | Programmable calling | Use a published call sequence or connect your SIP application. | Control calls through Voice API actions and events. | | Managed AI assistant builder | Connect the conversational runtime that owns your speech, model and tools. | Configure an assistant, model, voice and tools through the Telnyx portal. | | Business integration | Connect application decisions to a call and correlate the confirmed outcome. | Attach tools and dynamic variables to assistant conversations. | ## When is Telnyx a strong choice? Telnyx is a strong fit when you want its managed AI assistant runtime alongside telephony. Its assistant builder exposes speech settings and tool integrations; account for those capabilities when evaluating a different calling stack. ## When should you choose Bird? Choose Bird when you want the calling connection, routing and operational records alongside your existing Bird workspace. Use sequences for defined call behavior, or connect the conversational application you want to operate. Validate the complete workflow you need before replacing a dependency. ## Can I keep a Telnyx AI assistant unchanged? A Telnyx assistant is configured in Telnyx’s runtime. Moving a number or SIP connection does not copy its model, voice, tools or conversation settings into Bird. Decide whether to retain that runtime through a compatible connection or replace it as a separate integration. ## How should you compare the full cost? Start with the same destinations, call directions and expected duration. Include number rental, each connected leg, recording or transcription, and the speech and model runtime your design uses. A telephone-minute rate and a managed AI-conversation rate include different work; compare the total workflow. ## What does a careful migration involve? Inventory Voice API call actions, webhook handlers, SIP connections and AI Assistants. Record model, speech, dynamic-variable and tool dependencies separately from the numbers and carrier connection. ### Map the behavior Choose a Bird sequence for defined prompts and keypad decisions, or a SIP application for behavior you already own. If the application relies on Telnyx AI Assistants, preserve or replace that runtime deliberately and test its tools and conversation timing. ### Prove a complete call Use numbers you control to test audio, input, tool results, failure handling and the final record. Keep the old route available while validating the replacement. ### Plan the cutover Confirm number eligibility, porting or route changes, access and capacity. Preserve historical records and define how new call identities connect to your application.

A Telnyx assistant is configured in Telnyx’s runtime. Moving a number or SIP connection does not copy its model, voice, tools or conversation settings into Bird. Decide whether to retain that runtime through a compatible connection or replace it as a separate integration. ### Can I keep my current phone numbers? Number eligibility and portability depend on the country, number type and existing provider. Confirm the path before planning a port. A number move and an application migration are separate changes. ### How should I evaluate call quality? Test the destinations and clients your customers use. Check connection rates, audio in both directions, interruptions, keypad input and clean hangup. For AI calls, include speech recognition and response timing in the complete conversation test. ### Should I start with signup or a specialist? Use a Bird workspace for a controlled technical evaluation. Speak to a Voice specialist about number migration, AI runtime integration, production routing and capacity. ## Prepare the next step - [Migrate from Telnyx](/docs/guides/voice/migrate/telnyx): Inventory your integration, test the replacement and prepare a controlled cutover. - [Voice comparisons](/products/voice/compare): Compare the integration and operating model across providers. - [Voice resource library](/products/voice/resources): Find the setup, explanation and troubleshooting guide. ## Primary documentation [Telnyx calling documentation](https://developers.telnyx.com/docs/voice/programmable-voice/voice-api-fundamentals) [Telnyx workflow documentation](https://developers.telnyx.com/docs/inference/ai-assistants/no-code-voice-assistant) [Bird call sequences](/docs/guides/voice/call-sequences) [Bird AI voice integration](/docs/ai/voice-conversations) ## Plan your Telnyx migration.
