## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Good overview of the world of voice communications
  

*by M***A on Reviewed in the United States on January 12, 2015*

This book is a bit outdated since it is from the last decade but it met most of my objectives since I wanted to learn more about the fundamentals of voice communications including: PSTN, ISDN, PBXs, etc.This is not a introductory book for novices.I felt that this book was not proofread enough, i.e. the editors were not thorough enough as I did find quite a few errors: duplicate sentences, typos, o instead of 0, etc.

### ⭐⭐⭐⭐⭐ 







  
  
    Good buy!
  

*by M***E on Reviewed in the United States on March 22, 2020*

Received item as advertised & in a timely manner!

### ⭐⭐ 







  
  
    Thorough, not complete.
  

*by D***E on Reviewed in the United States on March 29, 2005*

After only 29 pages I found myself constantly asking "what is that, and when did the author define it?". Additionally, there are enough oddly worded sentences that I am unable to follow what is being said. Perhaps I am not the intended audience for the book, but since Sulkin did not include a forward, I can't tell. I am trying to use this as an initial guide to PBX, and find it lacking enought that I am now looking for another book.
