### AI overview

This article describes implementing a working, PTP-synchronized AES67/RAVENNA audio endpoint on the ESP32-P4 as an ESP-IDF component. It covers clock synchronization, low-latency packet reception, and I2S playout, reporting best-case end-to-end latency of about 0.7 ms and noting which parts are solid or still limited.

### Source excerpt

AES67/RAVENNA is the audio transport behind a lot of broadcast and live-sound infrastructure, and it normally runs on dedicated silicon or Linux boxes. This article is about getting a working, PTP-synchronized AES67 endpoint onto an ESP32-P4 -- how the clock sync, the low-latency receive path, and the I2S playout fit together, what the measured latency is, and where the edges are.

### AI overview

This tutorial explains how Voice over Internet Protocol (VoIP) carries digitized voice as data packets and examines common attacks against VoIP systems, including eavesdropping and SIP registration hijacking. It also discusses risks such as packet interception, identity spoofing, service disruption, and exposure of unencrypted signaling and audio traffic, while outlining the need for encryption, authentication, and monitoring.
