Quick Answer
Dante is a proprietary audio-over-IP ecosystem with tight product integration. AES67 is an interoperability standard that allows compatible devices from different ecosystems to exchange audio. They overlap, but they are not the same thing, and transport compatibility does not automatically mean discovery, control, QoS, or clocking behavior will match.
What It Is
Dante is widely used because it gives operators a consistent routing workflow across supported products. AES67 is narrower: it defines how compatible systems exchange PCM audio over RTP with common timing behavior, but it does not give you a full vendor ecosystem by itself.
That is why mixed AoIP networks can work well, but only after you verify what each device actually supports in its current firmware and operating mode.
Where Interoperability Gets Tricky
Many Dante products support some level of AES67 interoperability, but support is not universal and the details vary by device family and firmware. Even when the media transport is compatible, discovery and controller visibility may still differ between products and ecosystems.
In practice, that means you should verify four separate things before calling a mixed design "compatible": transport, discovery, clocking, and control.
A stream can be transport-compatible and still be awkward to discover, route, or monitor from the controller software you expect to use. Check the actual product documentation, not just the protocol name on the box.
How to Use Dante and AES67 Safely
- Confirm AES67 support on the exact device model and firmware version.
- Verify whether discovery is handled through Dante Controller, SAP, or another workflow.
- Check how clocking is expected to work in that mixed environment before you patch audio live.
- Use vendor QoS guidance for the products you are mixing instead of copying one DSCP recipe blindly.
QoS and Clocking
QoS is one of the most common failure points in mixed AoIP systems, but it is not safe to treat one DSCP map as universal across every vendor and every deployment. Dante and AES67-based products may have different queue expectations, timing profiles, and operational assumptions.
The safe approach is to follow the vendor guidance for the devices you are actually deploying, then validate clock stability and audio behavior on the real switch fabric. If you skip that step, the system may still pass audio in a quiet test and then fail under load.
Common Mistakes
- Assuming every Dante product supports AES67.
- Assuming transport compatibility also guarantees discovery compatibility.
- Copying DSCP values from another design without checking vendor guidance.
- Validating audio patching but not validating clock behavior.
