NAT problem still not solved,
This review is from: Inter-Asterisk Exchange (IAX): Deployment Scenarios in SIP-Enabled Networks (Wiley Series on Communications Networking & Distributed Systems) (Hardcover)
The most hindrance of voip acceptance is the infamous NAT problem. IAX does not solve it and can not as NATs are protocol agnostic. The author wants to give the impression that IAX solves a lot of problems SIP is having, like need for STUN and TURN servers. The truth is, IAX needs the same servers to alleviate the NAT problem. To the author's credibility he says with IAX the NAT problem is not worsened. That's true, but it's not made any better either. As I said, the NAT problem doesn't care about protocols and so IAX can't solve a whole class of problems at all.
If you want to buy this book because you think IAX can solve problems you are having with SIP then don't purchase. If you run an Asterisk server - which uses IAX internally and stems from (IAX = Inter Asterisk Exchange) - and want to know more about the IAX protocol then you might think about buying this book. But on the other hand, in this case it would suffice to read more about IAX on Wikipedia and run Wireshark in your network collecting IAX packages - the protocol is very simple. Most difficulties in a telephony environment are just mentioned but not explained at all. So I have to say the book is mostly a waste of time and money. |
