why fuss about the led's?
just buy a new sounder?
its either knacked,
led's on fly lead which have rotted off,
or made from components fitted in a decoy nova 4,
I'm a simple alarm monkey....
I've tried to get Homehubs & Thompson Tecicolours to work, however it cheaper for the sub for pay for a router rather than pay me to prat about...
Whilst very cheap & even cheaper to run when I get around to doing the long over due "pbx tart up" I'll use a mirco server rather than a pii
bought a couple of these http://www.ipchitchat.co.uk/GXP2140-IP-Telephone-p/gra-2140.htma while back, display is much better than the 2130
IIRC theres a console port in the back of the unit (light blue lead rg45-9 din pin)
& also a web client software but (IIRC) the unit has to be enabled for web?
However if its cisco you'll probably find somebodies paid to manage it
