I have a mix of IP phones (6921 and 7975) and IP Communicators (8.6) operating with CUCM 8.6. For my IP phones, DnD offers the option to either Reject Call, or just turn the Ringer Off. IP Communicator User guide indicates that the IP Communicators should support the same options, but, when I set them up, I'm only offered the Ringer Off option. Also, when set to the Ringer Off option, I'm given the option to have Beep notification, Flash notification, or Disable notification. If I select Disable, my IP Communicators still get Flash notification.
I'd really like to set all my endpoints to Reject Call. That's what I expect to be Do Not Disturb. As it is, the calling party has no indication DnD is in place, or a call is in place. They still get a ring tone, which indicates the called party is just not answering the phone.
Is there something ( a setting perhaps) that I'm missing?
Any help/advice is appreciated.
