I notice that the 5800 XpressMusic is not yet listed in the compatibility list. I tried anyway. Upon installing the internet pack I get an "certificate error" and when installing the Gzimo package itself (middle version; for 5700 XpressMusic), I get a message that the module is already built-in.
However, as far as I can tell, my XpressMusic 5800 only has the ability to configure a SIP server, but it is no used anywhere in the device, so that I am still without SIP calling ability.
Are there any plans to support the 5800 XpressMusic in the future?
