Started CCNA-V path, need some clarification on questions

2URGSE2URGSE Member Posts: 220 ■■■□□□□□□□
I started reading the book from Cisco for the CCNA-V, we are already using this system at work (Cisco VoIP) and while most of the material is clicking (I just started chapter 5), I have some questions.

1. They seem to throw a lot of terminology with the devices that store the software that's controlling the phone. I'm a bit lost here, I'm seeing the following:
  • CUCM
  • CME
  • CCM
  • Configuration files from a TFTP server. Where do I get the files????
Can someone please clarify these, which one is needed and when and what they do?

2. I'm in the process of expanding my lab so I can do voice. I guess I will have to sell my 2950's since they don't have PoE's....

I also figured I would need a 2800 Router or higher with FXO cards, RAM and the "software" I won't have to deal with Cisco (I don't have a support account with them)

The book also talks about a TFTP server for configuration files. I don't know a whole lot about VMware, would a PC or another laptop be ok?

Is there anything else needed?

    CUCM = Cisco Unified Communications Manager (CallManager) - Is responsible for routing calls between VoIP/non-VoIP phones, can control routers as voice gateways, and 1000 other things.

    CME = CallManager Express - A chopped down version of CallManager that runs on a Cisco ISR router. (For smaller environments)

    As for your configuration files they are needed for your phones to register with the CUCM (or Express) server which is typically also the TFTP server.

    Most people start off by playing with CME which is just a feature in your IOS image. Here's your list:

    1x 2811 (or 2821 if you can)
    1x POE switch (3560 is fine)
    2x 7942 or 7962 - Note the bold 2, these are java based and are less hassle then the older models (in my opinion), 7970 and above are also fine.
    1x FXO card (If you want to play around with analog interoperability and use your home phone line)
    1x FXS card (If you want to plug a regular analog phone or fax machine into your lab)

    Start with that and once you have gained enough confidence in the above areas we can get you started on CUCM, CUC, etc...
    My advice to anyone looking to advance their career would be to learn DevOps tools and methodologies. Learn how to write code in languages like Python and JavaScript. Not to be a programmer, but a network automation specialist who can do the job of 10 engineers in 1/3 of the time. Create a GitHub account, download PyCharm, play with Ansible, Chef, or Puppet. Automation isn't the future, it's here today and the landscape is changing dramatically.

    way overpriced. you can get a 3524 pwr for $50.00 a 1760 for about that much with CME. and if you shop right, get a 7960 IP phone with handset for $30.00. For the $300.00 they are charging for that "kit", you could score more 1760s with CME for remote sites, a 2600 with a NM-4AS for frame relay, and maybe a couple more 7940s an another switch. Shop around, there's always deals to be had. I know where you can get a 7960 with handset for $25.00 which includes shipping. 3 3524s for about $80.00 [not sure their power versions]. That ewaste harvesters on ebay. I've bought stuff from them in the past. Here's a 7960 for $25.00 at that ebayer. and he's got other Cisco stuff. But you do need a PoE switch if you don't get power bricks with the phones.

    Sorry but I wouldn't go anywhere near that generation of hardware for routers at least. Its just too darned old.

    You can get used 2801s for around 400USD, a few hundred more for WICs, DSPs and RAM/flash and you're set up to CCIE V level and will probably be OK for even the next exam revision. Also much better choice for any other track (R&S, security etc.)
