# Bird vs Plivo for Voice Bird brings SIP calling, defined call sequences and operational records into your Bird workspace. Connect the application you already operate, then keep its call outcomes beside the customer journeys that depend on them. [Start for Free](/dashboard/signup?returnTo=%2Fdashboard%2Fw%2Fvoice%2Fonboarding) [Contact sales](/demo?product=voice-migrate-plivo) ## Set up with your agent [Read the agent setup guide](/docs/ai/set-up-your-agent) Copy this prompt into your coding agent: ```text Bird connects customer communications, data and automation. 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-plivo 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 | Plivo | | --- | --- | --- | | SIP connection | Connect a supported SIP application through the Bird trunk configuration. | Use direction-specific inbound and outbound trunks. | | Inbound routing | Bind a receiving number to the intended SIP endpoint or call sequence. | Use primary and fallback origination URIs on an inbound trunk. | | Authentication and media | Configure the required credentials, source rules and compatible media path. | Associate outbound ACLs or credentials and configure TLS/SRTP through the trunk settings. | ## When is Plivo a strong choice? Plivo fits teams using Zentrunk’s inbound and outbound trunk model. Its API separates outbound access lists and credentials from inbound primary and fallback destinations, with explicit signaling and media security settings. ## 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. ## Is a Zentrunk object portable to Bird? No. Recreate the intended connection using Bird’s contract. Map direction, authentication, inbound destinations and media behavior individually. A similarly named field does not establish identical fallback, timeout or routing semantics. ## 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 inbound and outbound trunks, assigned phone numbers, access-control lists, credential lists, primary and fallback URIs and secure-media settings. Record any separate Plivo Voice API applications that control behavior behind the numbers. ### Map the behavior Map inbound origination and outbound calling separately. Recreate the client connection and receiving number route, then verify the transport, media and caller-identity requirements. Review any Voice API call instructions independently of the SIP trunk change. ### 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.

No. Recreate the intended connection using Bird’s contract. Map direction, authentication, inbound destinations and media behavior individually. A similarly named field does not establish identical fallback, timeout or routing semantics. ### 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. ### Does this comparison establish better call quality? No. The comparison describes documented product and integration choices. Test representative destinations, clients and audio paths to evaluate your own workload. ### 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 Plivo](/docs/guides/voice/migrate/plivo): 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 [Plivo calling documentation](https://www.plivo.com/docs/sip-trunking/api/trunks) [Plivo workflow documentation](https://www.plivo.com/docs/sip-trunking/concepts/technical-specifications) [Bird call sequences](/docs/guides/voice/call-sequences) [Bird AI voice integration](/docs/ai/voice-conversations) ## Plan your Plivo migration.
