    Hallo everybody,

    I can’t upgrade my CISCO ATA 186 from CISCO WEB site. I need version 2.16.

    Try this to upgrade to 2.16 is in my network and is working.


    1. Invoke the IVR by going offhook on the analog touchtone phone connected to port 0.
    2. Press the button on the top of the ATA 186.
    3. Key in the following on the touchtone phone to instruct the ATA to download software. 100#209*227*165*146*8000#
    4. Remain off hook while the ATA attempts to load the new software. The IVR will inform you whether the upgrade was successful or not.
    5. Once the IVR reports on the success of the upgrade, hang up the phone.

    Be careful with that 2.16 firmware, once you upgrade if you lose your password there is no known way to retrieve it, as the FACTRESET feature has been disabled.

    I have a problem between a Handytone 286 and the Cisco ATA 186. The people in Grandstream told me to upgrade to the latest firmware on the ATA because it doesn’t suppor branching. Do you know if some one has the 3.1 SIP firmware ????
