I have heard that there are plans to deprecate 7940,41,60 and 61 endpoints in CUCM release 14. I know many customers with very large estates that consist of almost entirely these models of phone. I know many customers who are considering Skype for Business as an alternative UC solution. Has any consideration been given to how the cost of being forced to replace thousands of phones will influence those customer's decisions on whether to stay with Cisco UC or move away to Skype for Business?
