how do i change the MOH for every phone on the CCM6.1.2.
in 5.1.3 i could do that on the device pool, but that option is not available in 6.1.2
Yes you can. Please refer to this link:
You can select BAT--> Phones--> Update Phones and do a query for the phones you want to update. Then on the " Field Descriptions for Update Phones" section you will find the User Hold Audio Source and Network Hold Audio Source.
