Hi,
Hopefully an easy question for someone. We've been shipped a 7821 IP phone but it's got the 3rd Party Call Control software on it. I'd read that I should be able to upgrade to enterprise using this:
http://<phone_ip>/admin/upgrade?<schema>://<serv_ip[:port]>/filepath
However, what is the schema referring to? Can anyone give me an example URL? Or let me know how to upgrade it to a normal software version. Our normal version is 10.3.1.12
Thanks, Will
