SIMBA + Twilio
Bring your Twilio phone numbers for inbound and outbound AI calls.
Twilio API docsSIMBA's Twilio integration bridges your existing Twilio phone numbers to SIMBA voice agents using TwiML <Connect><Stream>. You bring your own Twilio account — calls inbound to a Twilio number hit a SIMBA webhook, get routed to the assigned agent, and stream audio in both directions with sub-second latency. Outbound campaigns can originate calls through your Twilio account and hand them off to an agent with full context.
What agents can do
- Inbound voice calls with automatic agent routing
- Outbound voice campaigns with answer/voicemail detection
- SMS follow-up messages sent from the agent
- Call recording, transcription, and retention controls
- Works with verified caller IDs and toll-free numbers
Common workflows

</Response>Frequently asked questions
Do I need a SIMBA phone number, or can I use my own Twilio number?
Use your own. SIMBA is explicitly designed as bring-your-own-telephony — you keep ownership of the number and pay Twilio directly for minutes.
Is audio quality affected by the Twilio hop?
No meaningful impact. Latency stays sub-second end-to-end on warm infrastructure.
Does this support WhatsApp?
Yes. Twilio WhatsApp works with the same agent using a separate webhook endpoint.
Connect Twilio in the dashboard
Bring your own credentials. SIMBA stores them server-side and your agents call Twilio during conversations.
