I enjoy reading it, because there is a lot of info on things I don't understand. For example, it has an introductory description of how faxing works, then touches on how T.38 works with that approach. <br><br>There's also some information on what you'll usually see in equipment, and about movements afoot that aren't quite widespread as yet -- e.g., ENUM lookups for routing calls. <br><br>The author sprinkles in his opinions and technical/aesthetic tastes, however. While it's very informative, some sections read like opinion from a magazine like MacWorld. For example, the authors praise H.323 for its greatness, but criticize SIP for being as a bunch of vendor hacks. <br><br>But it's missing some key features -- like a useful index (it has one of those sparse six-page indexes for a 380-page book), or even a bibliography! The lack of a bibliography is particularly offensive. For example, the authors claim that "95% of VoIP minutes worldwide" are controlled with H.323, but provides no basis for that claim.</span></div><div><font class="Apple-style-span" face="verdana, arial, helvetica, sans-serif"><span class="Apple-style-span" style="font-size: small;"><br></span></font></div><div><font class="Apple-style-span" face="verdana, arial, helvetica, sans-serif"><span class="Apple-style-span" style="font-size: small;"><br></span></font></div><div><font class="Apple-style-span" face="verdana, arial, helvetica, sans-serif"><span class="Apple-style-span" style="font-size: small;"><br></span></font><div><div>On Aug 19, 2009, at 10:59 AM, Mark R Lindsey wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>"IP Telephony" by Hersent, &al., covers H.323 in some depth.
