Is there a way to add a Manager to a Call Queue that is already made.

Hello Andre, you can add and remove call queue members. Click HERE to know more. Thank you!

That is how to add members I need to add another manager?

Jenn was close - just look a little bit above on the Queue details:

You may also want to check the Notification email for the voicemails for the group - I found that if you have a distribution group set in exchange, you can add that email address, and any missed calls - that voicemail then goes to the dist_group.

When I click in there I only see my name and have no way of adding some one to the listing
