I have a DX120 system with Edge 120 phones. I have an extension always in DND. When I intercom that extension it rings once and then hangs up. The override (softkey) is not being displayed. In the Edge 120 manual it mentions "Some extensions with a higher Class Of Service may override the active DND condition." What class of service are they talking about?

Pressing FEATURE 4 will toggle the DND condition off and on. You may have a button labeled DND, but that is a programmable function and the programming may have been changed. Depending on the class of service programming, it is possible (via softkey under the display) to call a station in DND by overriding. I think what you want to do is take the station out of DND. You can do that with FEATURE 4.

Or Feature 69 then hit the interactive button under the word "go" on the display. That will default the set and reset all the features. If your feature buttons are programmed different from default, use feature # 3 to see how they are programmed first so you can re-program them after you do the default.

I put in a 120 a while back with v 20 software and had the same problem with one extension. DND would come on and station could not be called. Checked button, reset phone, still stayed in DND. Comdial tech support says it's a known issue with v20. Do you have VM on the system? The one I installed had VM. Comdial had me call into mailbox leave message, while you are leaving message hit VM key on set then pick up receiver and hang up. It removes DND. It's a known issue with them. There is a tech tip on the CC website that relates to the issue. They recommend to upgrade to v22. Tech support is aware of it. They are the ones that gave me the fix.

No, I don't think you understood the question. I know how to turn off the DND on the phone. But, I want to leave the phone in DND and then be able to override the DND via an intercom call. The manual says I can do this by hit the override softkey, but my phones do not display this softkey option. The manual also states "Some extensions with a higher Class Of Service may override the active DND condition." I not sure how to change the class of service?

Oh. The phone doing the over ride must have a higher class of service then the one being interupted. This is set in system programming by a certified tech, it's not an end user change.

Where in CA are you, Paul? You may be close to some certified techs who can help you get the problem resolved.
