Need CoolEditPro 2.1 editing help

I've recorded a conversation using my cell phone and the built-in mic on my Acer Windows 10 laptop. My guest sounds, as you would expect, like he's on a telephone. But the "phone" quality is in many cases raspy. I can usually tweak and edit silence and such pretty good, but I need help here.

I've tried several different settings but just can't get my guest's audio to sound less sharp, less "telephone-y" and simply more clear.

Any audio production experts out there who can give me what I hope will be a little simple guidance to clean this audio up?

The classic, what isn't there, can't be reproduced or created. Just as degraded pictures, can't be made original again, audio can't be made sound clear, if the source doesn't contain enough information.
In your case, the mic was bad quality, and now you have distortion, on top of it not sounding clear in the first place.
Graphics tools, and audio tools work the same way. They can "sharpen" things if the original source is somewhat of an average to good quality.
Sometimes, if the picture is somewhat clear, you can sharpen the picture to recognize, say, a number plate.
For audio, sometimes if there's too much (uniform!) background sound, you can remove it (if the vocals where of bad quality though, it won't restore vocals to good quality either), and the vocals may sound a tiny bit more clear. But as always, no matter how expensive the tool, there's no way to perform magical sharpening of a pixelated mess, nor create amazing vocals that was never captured in the first place.

So your only steps are, noise reduction, focus on the frequencies of the voice.and slightly amplify the volume. It will only help a bit, you will never get studio quality audio.
Amongst other things, a recording can sound  "telephone-y" due to lack of bass frequencies i.e. sounds "tinny".  There is an effect known as bass proximity effect.  The closer the sound source is to certain types of microphone the more lower frequencies are captured and boosted.  This is partly why radio broadcasters sound like Barry White and skinny kids with their lips almost wrapped around the microphone on stage and in their homes don't sound like the skinny kids they really are.   In days of old blues musicians would also sit facing into a corner singing into the microphone to accentuate bass frequencies.  Your audio source is probably lacking in bass frequencies partly due to the small diameter of the microphone and probably also the distance of the speaker from it.  You MIGHT be able to make it sound less  "telephone-y" by boosting some of those lower frrequencies, but you may end up causing the audio to distort in the process.  It might be worth a try.

Better late than never...thank you, gentlemen. I wound up talking with a radio engineer friend who took the audio and cleaned it up by boosting the low end (which did not make sense to my non-tech mind) but it worked well enough to get the job done.

The ultimate solution, thanks to his suggestion, seems to be a cell phone recording program named TapeACall. After you are on the line with the person you will interview, you call another number which records an mp3 of both parties. Then you can download it  and edit it, adjust volume etc much easier than most other ways.
Thank you George.  Glad you managed to have the quality improved.
