Hi All,<br>
<br>
I am looking to move Phones and Gateways onto a centralised CUCM cluster running 8.5 from 7.1. I have been looking at the Cisco Compatability matrix and it does not give you the minimum requirement for phone firmware or gateway IOS, it mentions 15.1(3) T as the minimum, I am sure you can use something lower. Does anyone know of any documentation out there that can provide this information?<br>
<br>
Regards<br>
