Existing telephony cannot reach the AI workflow
Use a compatible SIP connection to route calls into the configured application.
SIP trunking
SIP trunking for flexible AI call routing
Connect compatible SIP infrastructure to AI call flows and route voice through the carrier setup that fits your operation.
Direct answer
What this means in practice
SIP trunking connects internet-based telephony infrastructure to call applications so numbers and voice routes can reach configured AI or team workflows.Best for: Teams that already manage carrier relationships, need routing flexibility, or want to connect compatible telephony infrastructure to CallTurbo.
The operational problem
Why teams build this call workflow
Carrier choice is tied to the application
Separate the workflow layer from supported telephony routing where the integration allows it.
Routing changes are difficult to observe
Keep the call application and operational outcome visible in the same platform.
Implementation path
From call intent to a measurable outcome
Start narrow, make the handoff explicit, and expand only after the first route works reliably.
- 01
Confirm carrier and SIP compatibility.
- 02
Configure authentication, endpoints, codecs, and number routing.
- 03
Assign the SIP route to the intended call flow.
- 04
Test inbound, outbound, transfer, failure, and fallback behavior.
What to measure
Use outcomes, not call volume alone
A healthy phone workflow is judged by whether it reaches the intended next step without hiding failures or forcing every caller through automation.
- Connection successTrack by flow, route, and time period
- Call setup timeTrack by flow, route, and time period
- Audio qualityTrack by flow, route, and time period
- Transfer successTrack by flow, route, and time period
- Provider failure rateTrack by flow, route, and time period

Questions
SIP trunking for flexible AI call routing FAQ
Can I bring my own SIP trunk?
CallTurbo supports SIP connections, subject to provider compatibility and correct configuration.
Does SIP replace the AI voice provider?
Not necessarily. SIP handles telephony routing; voice, transcription, and intelligence can involve separate configured providers.
What should be tested before launch?
Test authentication, codec compatibility, caller ID, inbound and outbound routing, transfers, DTMF, timeouts, and failure paths.
Can multiple flows use SIP?
Routes can be assigned according to the number and application structure supported by your configuration.
