in the SIP headers for Call Leg 1 to track related calls
2. Using Twilio as a SIP Bridge
- Twilio can act as an intermediary to forward calls to Vapi.ai
- This approach doesn't require proxy authentication
3. Twilio as a Middle Layer
- Calls first route through Twilio, allowing AI to handle them in VAPI
- If human support is needed, Twilio can forward the live call to services like Genesys Cloud
4. Client Infrastructure to VAPI via SIP
- Calls can be routed from a client's infrastructure directly to VAPI via SIP
The specific route will depend on your configuration, including whether you're using Webhook or SIP settings in Twilio, and how your SIP trunking is configured.
Is there a specific aspect of the SIP routing with Twilio numbers you'd like me to elaborate on?
