Cisco DX650 Firmware: End-of-Life Status and Final Release Guide The Cisco DX650 was a unique all-in-one desktop collaboration device, combining a 7-inch Android-based touchscreen, a video conferencing endpoint, and a traditional desk phone. Released as part of the DX series, it ran a custom version of Android 4.2.2 (Jelly Bean) layered with Cisco’s collaboration interface. However, for current owners, the most critical fact is that the Cisco DX650 is End-of-Life (EOL). This has significant implications for firmware updates. End-of-Life Dates (Critical Context) Cisco announced the End-of-Sale for the DX650 on July 31, 2016 , and the End-of-Software Maintenance was reached on July 31, 2021 . This means:
No new firmware has been released since mid-2021. No security patches are being developed for the Android OS or the Cisco application layer. No technical support is available from Cisco for firmware-related issues (unless you have a very specific extended support contract).
The Final Firmware Release If you have a DX650 still in operation, the last stable firmware release is: Firmware Version: dx650-11-2-3-18 Based on: Android 4.2.2 Release Date: Approximately May 2021 This final build was primarily a maintenance release to fix a few lingering bugs related to SIP registration and video codec negotiation. No features were added in this release. How to Identify Your Current Firmware
Tap the Settings (gear icon) on the home screen. Navigate to About device or Phone info . Look for Firmware version or Software version . cisco dx650 firmware
How to Obtain DX650 Firmware (No Support Contract) Because the device is EOL, Cisco has moved the firmware to the EOL Software Download section of their website. You do not need a paid support contract to access EOL software. Steps to download:
Go to the official Cisco Software Download portal. Search for "DX650" (do not browse categories—the EOL section can be hidden). Select the device from the results. Choose the EOL Software tab. Download the latest .zip or .cop file (usually dx650-11-2-3-18.zip ).
Note: You will need a free Cisco account (Cisco Connection Online ID). Why Upgrade to the Final Firmware? Even though development is dead, upgrading to the final release (if you are on an older version) is recommended for these reasons: Cisco DX650 Firmware: End-of-Life Status and Final Release
Stability: The last builds fixed memory leaks that caused the device to reboot every few days. SIP Compatibility: Later firmware improved interoperability with modern SIP proxies (Asterisk, FreeSWITCH, BroadWorks). Certificate Updates: The final build included updated root CA certificates, critical for TLS registration to modern phone servers.
Critical Warning: Do Not Use This Device on the Public Internet This cannot be overstated: The DX650 runs Android 4.2.2, an operating system released in 2012. It has dozens of unpatched remote code execution vulnerabilities (e.g., KRACK, BlueBorne, Stagefright 2.0).
Only use this device on a fully isolated VLAN behind a corporate firewall with no direct internet access. Never load third-party Android apps on it (the app store is long deprecated). Use it strictly as a SIP desk phone and internal video endpoint . This has significant implications for firmware updates
Common Firmware Upgrade Issues & Fixes | Issue | Likely Cause | Solution | | :--- | :--- | :--- | | Upgrade fails at 5% | TFTP server timeout | Use a local HTTP server (like IIS or Python http.server ) instead of TFTP. | | Device boot loops after upgrade | Corrupted download | Re-download the firmware .zip; check the MD5 checksum against Cisco’s published value. | | "Invalid signature" error | Unit is running very old bootloader | You must flash an intermediate firmware (e.g., v10.x) before jumping to v11.x. | | Upgrade completes but Android crashes | Factory reset required | After upgrade, perform a "Factory Reset" from the bootloader menu. | Better Alternatives to the DX650 Given its EOL status, consider retiring the DX650. Modern equivalents include:
Cisco Desk Pro (current model, runs RoomOS) Poly Studio X30 (similar all-in-one) Yealink VP59 (lower cost, Android 9+)
