Also in studying solely Cisco's use(or misuse) of VoIP, you're locked
into a Cisco world which means nothing in terms of understanding VoIP
from the protocol level as a whole.
Here are some of the books floating around my house and work that I
constantly use when it comes to VoIP. Things to consider from this short
list though, I come from a systems administrator, network
administration, security administration/engineering background. I'm not
particular about any one specific vendor. More of a "get it working now".
Securing VoIP Networks - 0-321-43734-9
SIP Handbook: Services, Technologies, and Security of Session Initiation
Protocol - 142006603X
Practical VoIP Security - 1597490601
Telecommunications and Data Communications Handbook - 978-0-470-04141-3
(excellent book and reference guide)
I'm sure I'm not alone on this list - from the ITSP level - today I
could be assisting and or configuring an Avaya trunk or PBX followed by
Cisco trunk or PBX to say: Iwatsu, Asterisk, Nortel, etc.. I find it
better and easier to understand the specifics of a vendor's offering
just by understanding the underlying protocols. For that, I refer to the
ever boring, long and drawn out RFC's., running Wild Packets or
Wireshark and understanding IP, SIP packets as a whole. When all my
books and Google fail, I go to my colleague who fills me in on all I'm
missing or misunderstanding on VoIP - so it pays to surround yourself
with knowledgeable people.
