I would suggest picking up all three books as pdf.  Mine are left open on my desktop all the time for reference

Original 1.2 book

Alternative endpoints 264

Skype and GSM endpoints 264

Skype with mod_skypopen 265

GSM with mod_gsmopen 266

TDM with OpenZAP and FreeTDM 267

Subject: [Freeswitch-users] Question about the latest FreeSWITCH book

Can anyone having the book let me know if it has material on mod_gsmopen ? It doesn't seem to be a module that many people use, and not sure the book would cover all modules, but it is what I am very interested in.

I am looking at the general architecture, design principles, configuration etc. Basically something, that is not there in the Wiki.
