I have a couple of extensions that can not be dialed from the company menu. When I dial into the menu and the system prompts for the extension, I enter the extension and it just pauses and rings back into the main menu. Any ideas to point me in a direct to look at?
Danny is correct, you will have to set them up with a voicemail box in order to have them available in the directory/auto attendant.
I know it is not what you want, but that is the fix.
Are you using Cisco Unity for your AutoAttendant ? if you are using Cisco Unity then you need to set up either a callhandler or a voicemail box for each of those extensions in order for you to be able dial those extensions from the AutoAttendant.
Hope that helps !!
