I'm stumped on this one...user one has established a conference call, total on call..three people...when he tries to add an internal person (call the internal person 2222) to the conference call he cannot. This is a continuing problem only with extension 2222. I've checked 2222's station profile and it is no different than others in the office. When others have tried to establish a conference call with extension 2222 they fail as well.
Any suggestions?
