Is it possible to determine whether a phone call is local or long distance by analyzing the audio?

Question: Is it possible to determine whether a phone call is local or 
long distance by analyzing the audio?

Please see the thread:

"If only I could cleanup this audio, I could solve the JFK assassination..."

in comp.dsp and rec.audio.pro for details.

Perhaps there is a related newsgroup?

TIA,

-Ramon
