Twilio से Voice माइग्रेट करें

Help me evaluate a Voice migration from Twilio to Bird.
1. Read https://bird.com/docs/guides/voice/migrate/twilio.md. Use the .md alternatives of linked Bird guides for the steps below.
2. Check for a connected Bird MCP server or an installed, signed-in Bird CLI. Use whichever is available and discover its tools or command help. If neither is available, follow https://bird.com/docs/ai/set-up-your-agent.md. Do not invent operation names or install a second integration.
3. Perform a read-only inventory of my current call sites, numbers, SIP configuration, call-control instructions, event handlers, recordings, speech services and business tools. Identify secrets without printing them. Show the dependencies that stay with Twilio and the ones that need replacement.
4. Read https://bird.com/docs/guides/voice/sip-trunks.md, https://bird.com/docs/guides/voice/placing-calls.md and https://bird.com/docs/guides/voice/receiving-calls.md. Prepare the replacement connection and caller-identity requirements. Use https://bird.com/docs/guides/voice/call-sequences.md for defined menus and https://bird.com/docs/ai/voice-conversations.md for a conversational runtime. Verify each operation against the connected surface before proposing an executable step.
5. Prepare a test of one complete journey: setup, audio in both directions, keypad input, unanswered and failure paths, handoff where needed, and business-tool results. Show the exact target, configuration and expected cost before placing a call or recording audio; wait for my approval. Do not buy numbers, submit a port, change production routing or stop the existing provider without my explicit approval.
6. Use https://bird.com/docs/guides/voice/events.md and https://bird.com/docs/guides/voice/call-log.md to reconcile the outcome. Keep missing evidence and uncertain results visible. A spoken confirmation is not proof that a business action succeeded.
7. Return the integration differences, test evidence, unresolved requirements and rollback plan. Keep the current service running until I approve cutover. If a number port needs support, inspect the available support command or tool, prepare the exact request and ask for approval before submitting it. Return the ticket reference if authorized; a ticket does not schedule or complete a port.
