Hello all,

I am wondering the compatibility here,  will the devices below be working with UC 10.5 ?    

Any one has real world experience?        Your information and help is highly appreciated.

Those are the versions the BU tested and guarantees functionality to work, this does not mean older versions will not work, only that in case of trouble, TAC reserves the right to ask you to upgrade to the mentioned version, before continuing with the troubleshooting.
