While this is sad, to say at least, it is not really that bad as someone may think, because the good news is that we can use virtual routers as IPIP gateways to simulate PSTN switch behavior and provide H.323/SIP signaling interface to CCM. Of course, we cannot simulate NM-HDVs, PVDMs, FXO/FXS or E1/T1 digital trunks with Dynamips (yet). Next, for the routers emulation, we can use the product everyone loves - Dynamips. To begin with, we can run CCM and Unity under VMware, as well as use SCCP softphones to simulate the real 7960. Is there anything we could do to offload a deal of work to virtual routers and servers? Definitely, there is a lot of it. Let us hold for a second and think about virtualization.

Now do not fall into despair, and take a quick look on a list of things that you need for a full-blown voice rack: Ĭatalyst 6503 SUP2 with 6608/6348 blades Catalyst 3560 PoE Bunch of 2811 with NM-HDV2/PVDM2s and WIC-2MFT-T1/E1 About six 7960 IP Phones At least one ATA 186 VG 248 gateway NM-CUE or AIM-CUE Three servers to run CCM Publisher/Subscriber and Unity Too many of it, not to mention, that it’s probably going to cost some big money to obtain.

You got a moment to look at the list of the lab gear, and now it does not look so good anymore. It takes some time, but you pass the written test, and plan to take the lab exam. You decide to go after your Voice CCIE, and nothing can stop you. HOWTO on Virtual Voice Rack Petr Lapukhov CCIE #16379 (R&S/Security/SP) InternetworkExpert Inc.
