Hi,

 

We are using 9.X CUCM version and we are migrating into SIP, we have sip trunks, ATA 187 Sip phones, cube,CUSP etc. and now we have started migrating conference 7937 ip phones to Cisco 8831 sip phone.

 

But we are facing a major issue, FAC enabled conference phones (8831) can view the FAC code in the screen when we enter the FAC code which is insecure, do you have any fix for this or any alternate solution. In the forum i came to know this is a bug.
