I purchased a GT-1900u today from Marlin. I mistakenly thought it would work
for all voip providers, it does not work for my xlite softtfone or my
voipbuster/voipcheap. Anyone know if it can be made to work for these and
others or have I made a mistake. It is obviously my own fault for not
reading the small print prior to ordering. I wonder if anyone can help or I
will just sell it off cheap.
