I currently have a Cisco UC520 running the CME 7.0(0). I have a 7975 connect and that is able to make calls and get a extension but my 7920's running firmware 7920.4.0-03-02 are able to connect to the UC520 but are not getting a extension andor able to make calls. I for the life of me can not figure this out and thought maybe I could gather some help from the community on this.
Re: Cisco 7920 Unable to make call or get extension
To piggy back on Blakes comment. Is it getting an IP and can you ping it .. If so let us know and then we can take further. If not, we need to get it on the network.
