Connect your existing phone numbers with SIP trunk

You can now connect your existing phone numbers to your Chatbase AI voice agent using SIP (Session Initiation Protocol) trunk.

If you already have numbers with a SIP provider, PBX, or GSM gateway, add the number under Deploy → Phone and point your trunk at the SIP URI Chatbase generates. Incoming calls will be answered by your AI agent using its configured voice, personality, and knowledge.

This makes it easy to use Chatbase with your existing telephony infrastructure, integrate with call centers, and keep your existing phone numbers.
