At about the same effort, you can be even more secure. Use cash. Change your $20 bill for a couple rolls of quarters and walk up to any pay phone that takes coins. Put in a quarter, and dial your number. You'll hear something like 'Please insert $3.50 for the first three minutes.' Shove in the coins, and talk. Works fine for long distance as well as local calls. Much cheaper than the 900#.
If you use a calling card for more than a single call, those calls can be linked to each other. It may also be possible to trace where the card was sold.

Also, even the private-switch operations selling cash-paid calling cards have records of the calls made on their systems, though those records might not be in a form that makes them readily linkable to the orginator of a given call--it all depends on how much it's worth to the pursuer to pursue you.
