[cisco-voip] SX20 Telepresence software upgrade

[James Dust]

Afternoon all,

I am trying to upgrade some SX20 devices on our 8.6.2 cucm cluster from version TC5.1.5 to TC6.1.1 but am encountering difficulties. I have installed the new software on all cucm nodes and hard reset/factory reset the SX20's to try and get them to upgrade but they don't pick up the new default software image.

Has anyone else encountered this problem? And if so what do you need to do?

On a side note I realise you need to update the release key for the device when you upgrade and have this covered.

Kind regards

James
