I was wondering if there is a way to beef up the sound of a telephone conversation recorded through a phone patch. And "By beef up" (Wow such technical terms!) is there a recommended EQ setting I could use as a starting point? Bare in mind of course that telephone line frequencies are very thin when compared to a VO recorded by a mic. There aren't as many frequencies transferred across a thin telephone line cord so the recording leaves less to EQ. What would be the best way to proceed?
I usually use the following audio workflow...
4)Compressor & or Limiter if needed
Your thoughts would be greatly appreciated. Thanks for you time!

Unfortunately, we can't boost what is no longer there. I really wish we could every time I work with phone audio. The best I've found I could do is to work with a multiband dynamics processor, namely Waves C4, and combine compression of the high-mid and what little highs there are in a phone signal with a slight expansion in the lower mids. That comes after noise reduction, of course. If it sounds really harsh, using a sidechained compressor as for de-essing takes the edge off. I don't compress or limit the result, personally, as anything recorded through a phone is already compressed a fair bit. But I generally hate working on phone audio as I like to output good audio and it's pretty much impossible with phone audio. The damage is already done. There is no magic technique that makes it sound great. If there is, I most definitely want to learn it.
Try the JK "Audio Box" or Jake Box. It is a telephone/pro audio interface. Has line level xlr inputs, a null control for the telephone signal. Individual pots for the xlr inputs (3). Has xlr outs, you can use it has a mixer. Signal stays strong and clear.
