Hi there! 👋 I don't have information about a single definitive SIP route, as it varies based on your specific configuration. However, I can share several potential routes and factors that influence SIP routing when calling a user with a Twilio number. According to the information I found, here are some potential SIP routes and relevant details: ### Common SIP Routes with Twilio 1. Initial Call Routing via Twilio to VAPI - The initial call (Call Leg 1) is routed to VAPI from Twilio or another SIP provider - VAPI then forwards the call to the destination (Call Leg 2), creating a new Twilio Call SID - You can pass
X-Call-ID: <unique-id>
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?
