have you tried the network cable feeding the yealink in a laptop or PC, to verify the network connection is actually good?
when testing cables you have to consider the entire length back to the router or switch, including any internal wiring, you can test this by taking the yealink and plugging it in to the router directly, bypassing and switches and internal cables
you can by the TA100's at PB tech by the looks of it for less than 100, but if you're prepared to do that you may as well try a factory reset on it first. Whether it works or not (ie regardless of whether it is configured) , you should still be able to access the web interface - if you can't there is probably little point in testing the phone side just yet...

This world would be a perfect place if it wasn't for the people.
