I'd like to start this blog by note about, from my point of view, the one of the important components extremely needed for successful preparation for the voice track - Lab Environment.
If you are preparing to the CVOICE Exam (v6/v8) it would be great if you have couple of Cisco ISR with PVDM2 module(s) and some Cisco IP Phones 79xx. If you are lucky, you also have several VWIC(2)-(X)MFT-T1/E1 modules, and maybe some FXO/FXS modules to connect analog devices.
If the above is not available, I strongly recommend you to practice with GNS3, which can emulate Cisco VoIP Router (but without DSP, T1/E1 and FXS/FXO), let say ISR 2801. In conjunction with Cisco IP Communicator (CIPC) you can study not all but many important topics.
If you are preparing to take the CIPT1/2 Exams (v6/v8) you just need to practice with CUCM. It can be done with free VMware products, such as VMware Server 2 or VMware vSphere Hypervisor (ESXi).
To be continued...
