I have a Grandstream UCM-6108 Asterick based pbx and seven Grandstream GPX-2135 phones.
My system was setup by the selling dealer who has since gone out of business. My problem is that all seven of our GPX-2135’s are suffering from fading LCD screens.
Because I have no selling dealer I was not able to get any tech support from Grandstream, until very recently when I was able to contact someone at Grandstream North America who is willing to help (thanks Twitter).
Anyway, he is sending one GPX-2135 to see if I can clone it.
Now my question: How does one use the UCM-6108 to ‘clone’ one of my failing GPX-2135’s to make the new phone identical to the old one.
