Yes — you can connect non-Twilio numbers using SIP trunking.
SIP trunking allows you to establish a direct connection between your telephony infrastructure and the ElevenLabs platform. This means you can route inbound calls from any supported phone number — even if it's not hosted on Twilio — to your Conversational AI.
Using SIP trunking, you're not limited to Twilio numbers and can integrate with existing carriers or on-premise systems.
For more information on the setup of SIP trunking, please see our Conversational AI documentation.
