You can do basic stuff on CME 4.x but exam is based on CME 8.
then you need just regular PC, at least dual-core and 8 GB Ram should be OK for CCNA Voice;
you just need to run 3 VMs. a CUCM and another one for Voice mail and Windows AD server.
see my post in https://learningnetwork.cisco.com/thread/36652
I have been trying so hard to get an all in one list of everything that I need to get this lab set up ... I dont have much voice experience so alot of this is new to me. From what you have said on other posts I think I have a grip on it, but at the same time I am missing a couple of things and I wanted to verify a topology that would be used.
1) 2811 with: IOS 15, 256/128, CME8, FXO, PVDM-8, AIM2-CUE (with CUE on flash), FXS.
2) 3550 switch
3) Two 7940 4-button phones
4) Analog phone
5) PC with IP Phone software (Personal Communicator ?)
6) VMWARE / ESXi to run: Windows AD Server, CUCM 8.6, CUC, and CUP
So the topology would be to connect the switch to the 2811 router and the IP phones and PC to switch. The POTS line comes in to the FXO and the analog phone is connected to the FXS - both on the 2811. All the virtual machines are on the switch as well. Is there not a need for a 2nd switch and or router, or is this enough to cover all the exam topics?
