Finally moving back to the VoIP World

I haven't posted in a while but I finished up the TCP/IP Vol 1 book going through the subjects that I feel I needed to review before going back to VoIP. Mainly the interior routing protocols and overview regarding redistribution and basic static routing. This was all for making sure I had foundation for building on my VoIP knowledge to tackle the CCNP: Voice and maybe the CCIE: Voice. How can you sufficiently route voice over IP packets if you don't know how to route IP packets on its own?

I feel comfortable enough with IP routing to start diving deep into the Voice world and I have. It doesn't appear that the new CCNP: Voice reading material is quite done yet so I'm starting with Cisco Solution Reference Network Designs (SRND) material. These are really good free reading material providing best practices and design for all types of network solutions from security, voice, routing/switching, wireless, etc. Also moving to a new place leaves you pretty broke for a while and I know I'm going to have to drop some $$$ for additional lab equipment, books, and the 4 test to become CCNP: Voice certified. So I'm saving up money now while I scavenge the internet for free material!

I started with the Cisco 8.x CUCM SRND last week and I'm already at page 148 (1356 pages total) putting in about an hour of study a day.

Today I started on the security section for both the access layer and phone level. Talks about many basic things such as Man in the Middle Attacks, port security, disabling phone PC ports, etc. Tomorrow I'll read through material regarding Access Lists (ACLs) in a Unifed Communication environment.
