How Bird and Bandwidth compare across voice workflows

Compare how each provider connects your SIP equipment, routes incoming calls, and integrates with AI voice runtimes.

Funktion	Bird	Bandwidth
SIP-Verbindung	Connect your PBX, contact center, or voice AI media server to a dedicated SIP domain with IP allowlists or digest authentication.	Connect a SIP client through a configured realm and SIP credentials.
Eingehendes Routing	Bind each phone number directly to a SIP trunk endpoint or a published IVR call sequence.	Konfigurieren Sie priorisierte Routen und gewichtete Endpunkte für eingehende Anrufe.
KI-Runtime-Integration	Bridge inbound and outbound phone calls over SIP to the voice AI runtime that runs your speech model and tools.	Bandwidth's documented Vapi integration uses Bandwidth for SIP telephony and Vapi for the assistant.

Wann ist Bandwidth eine gute Wahl?

Bandwidth fits teams that already manage calling through its SIP realms, prioritized route tables, and weighted endpoint groups, or follow its documented Vapi SIP setup for external voice assistants.

Wann sollten Sie Bird wählen?

Choose Bird when you want SIP trunking, hosted IVR call sequences, and call recordings in the same workspace and API key as your SMS, WhatsApp, and email messaging. You can route numbers to your existing PBX or AI voice server while triggering follow-up texts or emails from the same platform.

Kann ich meine bestehende PBX oder KI-Runtime behalten?

Yes, if your PBX or AI voice server supports standard SIP signaling and compatible media codecs. Point a test trunk at your equipment, configure IP allowlists or digest credentials, and verify inbound dialing, outbound caller ID, two-way audio, and call transfers on a pilot number before moving live traffic.

Wie sollten Sie die Gesamtkosten vergleichen?

Price the complete call using your real destination countries, inbound and outbound call mix, and average call length. Include monthly phone number rental, per-minute carrier charges for each connected call leg, recording or transcription fees, and the speech and LLM costs from your AI runtime.

Was umfasst eine sorgfältige Migration?

List your Bandwidth SIP realms, credential sets, inbound route priorities, endpoint weights, phone number assignments, and any Programmable Voice call control before you start moving traffic.

Map inbound and outbound trunks

Create a Bird SIP trunk for your PBX or AI voice runtime, configure IP allowlists or digest credentials, and set your outbound country allowlist and verified caller IDs.

Test a complete call end to end

Assign a test number in Bird and place real inbound and outbound calls to verify two-way audio, keypad input, agent tool calls, transfer handling, and call detail records while Bandwidth still serves production.

Port numbers and cut over traffic

Check number portability for each country, bind imported or newly provisioned numbers to your verified Bird trunk or sequence, and shift outbound traffic in stages.

Fragen zu Bird und Bandwidth

Kann ich meine bestehende PBX oder KI-Runtime behalten?

Kann ich meine aktuellen Rufnummern behalten?

Portability depends on the country, number type, and losing carrier rules. Check eligibility with Bird before scheduling your cutover, and test your SIP trunk and call routing on a temporary Bird number first while your porting request is processed.

How do I evaluate call quality before switching?

Place test calls to your actual destination countries through the same PBX or AI voice server you run in production. Verify connection latency, two-way audio clarity, DTMF keypad recognition, and disconnect codes on a pilot number before moving live customer traffic.

Should I start self-serve or talk to a Voice specialist?

Start in a Bird workspace to provision a test number, configure a SIP trunk, or publish a call sequence. Contact our Voice team when you are ready to plan multi-country number porting, concurrent call capacity, or custom routing.
