Hi all,
In order to get a 6900 series phone to work on the MiVO 250 or 400 systems, they have to be flashed with SIP firmware - no problem.
However I've been given a phone which has been flashed with the SIP firmware and need to get this back working on a MiVoice Business.
Has anyone re-flashed these back to MiNet and got any idea where to start?
