HI,
I've just bought some refurbed LG LDP7008D handsets but when I plug them into a port where an existing phone (same model) works then the replacements one's stick at a message that ends in "NO SYNC". The only thing that appears different on the display of the existing phone (before it says "OK SYNC" and then flicks to the normal extension display) is that the existing phones say that they are V1.4 on the top line and the replacements say they are V1.0A.
Is this a problem with incompatible firmware (in which case can the firmware be upgraded?) or are there any settings that can be applied to the phone to make it work or are they just totally incompatible?
Thanks
