Sensors listen to RTP streams and do not process signaling traffic; therefore, sensors cannot distinguish the caller from the called party. When packets stream into a switch, the far end is the speaker and the near end is the listener and vice-versa. Cisco Unified CallManager is a call agent and recognizes Caller and Called endpoints.
