Default Need help removing a periodic noise

You know that annoying sound that a Nextel cell phone makes if it is
too close to your car stereo or computer speakers? I need to remove
that noise from a recording! It's a tough task, here's what I've
tried so far:
1) Spectrum analysis of the noise shows it is all over the audio
band, so eq is not helpful.
2) I copied an individual instance of the sound, inverted the phase,
and mixed it with the original. This of course worked, but each
"click" is unique, and the rate changes slightly over time.

Here's what it sounds like:

Any help is greatly appreciated!
