I guess Paula is right Well Darrell, I am guessing it's a very simple question !! I might be wrong But I'll try to close the discussion with one statement: Whenever you're using the Web GUI, you have the flexibility to choose the protocol being used to make the call. You can either choose SIP or H.323 which ever is set on your endpoint correctly. However, when you use the codec itself to make the call, the default protocol is used to make that call. I bet that your default protocol is set to something which you have not setup. You can change that using this command: xConfiguration Conference 1 DefaultCall Protocol: <H323/Sip/H320> Hope this answers your question Thanks Mubashshir Akhtar ... View more

Hi Mohamed, The procedure above is for the devices running TC5.1 and above. Can you verify what is the version of the software running on your device? You can give a try with this old method: By using the power button (Prior to TC5.1) Unplug power cable Replug power cable Imediately when the green led in the bottom left corner lights up, press and hold the power button for 10 seconds (the led will turn off), until the green led lights up again. Push the power button twice within two seconds (two short pushes) If your device is running a software prior to TC5.1, this method should work for you. Thanks Mubashshir Akhtar ... View more
