title: Cisco Voice Portal Call Control SIP Sessions API
description: The Cisco Unified Customer Voice Portal (CVP) Call Control API provides programmatic access to call control functions on the CVP Call Server. The Call Server is the SIP-based call control component that manages call routing, transfers, and session management within the CVP deployment. It integrates with Cisco Unified ICM/UCCE for intelligent call routing and with Cisco Unified Communications Manager (CUCM) for agent delivery. This API exposes management and monitoring operations for active call sessions and call routing configuration on the Call Server component, typically accessible on port 8000.
