Call detail systems — call detail record (CDR) capture, call logging, call recording, and telephony analytics — run continuously, often for months without a reboot. The computer behind that workload must do three things reliably: stay powered on, capture data from telephony interfaces without dropping a packet, and survive an office or factory-floor environment where dust and heat are normal. A fanless industrial PC or mini PC with a low-power Intel processor, dual Gigabit Ethernet, and wide-voltage DC input is the standard answer for this class of deployment.
What These Systems Actually Log
A call detail record captures metadata about each call: calling and called numbers, start and end timestamps, duration, trunk or extension used, disposition (answered, busy, no answer, failed), and increasingly call quality metrics such as jitter, packet loss and mean opinion score (MOS). In VoIP and unified-communications environments that data
