So I've just discovered that the OSS Endpoint Manager has support for Yealink T46G.
https://github.com/provisioner/Provisioner/tree/master/endpoint/yealinkv70/t4x indicates that it needs firmware V70.
Is anyone aware of where I can download this firmware? http://www.yealink.com/SupportDownloadfiles_detail.aspx?CateId=310&flag=142 only seems to list V71 and V72 (28.71.xxxx and 28.72.xxxx which I am guessing are V71 and V72)
