How to Transfer Calls in AI Voice Agents Using SIP Telephony

Call Transfer in VideoSDK enhances AI voice agents by allowing them to seamlessly transfer ongoing SIP calls to the appropriate person without disconnecting the caller, ensuring a smooth and uninterrupted conversation flow. This feature is crucial for callers seeking quick resolutions, as it prevents the need to redial or repeat information. The system works by having the AI agent assess the user's intent, then using a function tool to direct the call to the correct number while maintaining the session. The implementation involves setting up call handling, outbound calling, and routing rules using tools and classes provided by VideoSDK, including the CallTransferAgent, which is designed to facilitate these transfers efficiently. This capability transforms AI agents from mere responders into robust call-handling systems, reducing awkward transitions and enhancing user experience.
