asterisk users - Mar 2008 - phones start ringing randomly with Grandstream GXW-40XX - solution!

Thought i would share this so it doesnt annoy others as much as it did me :)

If you recently installed a GXW 40XX and your extensions start ringing  
magically now (ringing for no reason, pick it up its a clear tone) you  
need to check the "Disable send MWI" in your gateway. apparently  
certain old phones do not like the MWI signal and treat it like a ring  
tone.
