No I don’t, but you don’t really have to if you’re using EQ and know what the purpose of the sound needs to be.

Eq is very simple: People can hear from roughly 20Hz (very low) to 20000Hz (very high). Your speakers can probably produce something like that as well.

A human voice roughly reaches from 80Hz (low men voice) to 12000Hz (the high part of the pronunciation of the letters s and t)

An old telephone line reaches from 300Hz to 3500Hz (the telephone sound) which is 90% of all the sound you need.

So start by lowering everything else but the telephone range frequencies. Then slowly add some of the other frequencies until it does start to sound naturally.
