NDG has developed CVOICE Labs to support the CCNP Voice Certification. The CVOICEv8.0 642-437 course is part of the CCNP Voice Certification. The CVOICE course provides an excellent introduction to Voice over IP and QoS technologies. The NDG CVOICE Labs were written to correspond with the chapters in the official certification book, Implementing Cisco Unified Communications Voice over IP and QoS (CVOICE). Therefore, you can use this book along with the NDG CVOICE labs library to teach the CVOICE course.
The routers used must meet minimum IOS requirements specified in the Multi-purpose Academy Pod (MAP) for Voice over IP. The equipment recommendations provided here are based on research conducted at NDG's lab. Those who purchase voice devices maintain full responsibility for verifying the compatibility of all parts recommended. Other router and switch models may be used.
The lab device recommendations in this section may be used if you plan to teach CVOICE 8.0.
|256 MB||15.0(1)M5||IOS 15 with voice license|
|256 MB||12.4(24)T5||IOS 12.4 Advanced IP Services2|
|R2||Cisco 1841 or superior||128 MB||256 MB||12.4(20)T1||IP Base|
1CVOICE Lab 6: Using Gatekeepers requires the IOS ?c2800nm-adventerprisek9_ivs_li-mz.124-24.T5.bin?, which includes the H.323 Gatekeeper functionality. This IOS was tested on a 2811 with 512MB DRAM and 256MB flash memory. To perform Lab 6, you must download this specific IOS, and make it available in R1?s flash memory. You should create a directory in R1?s flash memory called ?/IOSs/? and store the IOS in it.
2It is possible that you can run the IOS 12.4 Advanced IP services with 256MB of DRAM on a 2811, and 192MB on a 2801. However, the testing done to support the NDG CVOICE Labs used 512MB and 384MB respectively.

Please refer to the recommendations provided for the Multi-purpose Academy Pod (MAP) for Voice over IP for details on voice equipment options to consider, including Basic and Premium bundle options for upgrading a MAP pod to teach CVOICE v8.0
Create a new class to be used for the CVOICE Course using the following settings:
The Multi-purpose Academy Pod (MAP) for VoIP is also available for "pod-only" reservations. To enable pod-only reservations, select the check box for the following option in the class settings that are appropriate for the pods available on your system:
"Pod-only" reservations are not tied to specific lab exercises. Therefore, the pod will be configured using the default network configuration and will not be properly configured to complete NDG CVOICE labs.
More information is available in the Enable Multi-purpose Academy
Pod Exercises section of the
Multi-purpose Academy Pod Planning and Installation Guide
Always select the correct lab exercise for the lab being performed. Students or teams should schedule the correct lab exercise from the catalog. NETLAB+ will only show those labs for which the required pod type is available. A lab that works on different pod types may appear more than once if your system is so equipped. Instructors should select the correct lab from the Exercise tab during instructor-led lab reservations. This can be done as many times as needed during the reservation.
Importance of Choosing the Correct Lab Exercise
Several of the labs may differ from the standard pod topologies. This is handled by NETLAB+ Dynamic VLAN Mapping technology. Always select the correct lab exercise for the actual lab. This insures that NETLAB+ will set up VLANs on the control switch such that lab devices and PCs are placed in the correct LAN segment for the exercise being performed. Selecting the correct exercise will also make the completed lab output easier to find in the archive.
NETLAB+ will configure the routers and switches with initial configuration files that include basic IP connectivity. Please verify this configuration by pinging the network interfaces before starting the lab exercise.
