Sounds like your phone needs either a aux power source to power that
led, or possible a little modification to clip that LED.

I would make sure your cordless phone's power supply is within spec. If
it is, Maybe you might want to look into one of the other comments a
while back on the list about upping the power on the SLIC(?). You might
be able to provide enough power to the phone to not cause trouble when
it blinks the LED.
