Hi all.
I would like to buy a good book about SIP.
I have read in this list that "Internet Communication Using SIP: Delivering VoIP and Multimedia Services with Session Initiation Protocol" by Henry Sinnreich and Alan B. Johnston is a really good one.
Does anyone know another better ?
Thanks in advance.
Kiko
PS: please, someone answers my previous post which ask if with NATHELPER + RTPROXY is possible to establish videoconference sessions and not only audio sessions and if this is solved with Mediaproxy.
A bunch of thanks !
