    CCNA Voice, VCP5
    #26
    Well, my lab budget is spent. I think I have everything I'll need except a second 2950 switch and ip phones+bricks. I have a 2924 XL from my CCNA lab that I can use, and I can always use Cisco IP Communicator in-place of real phones. I would love to have had the money for Unity Express, but I'm hoping I can just study those sections closely and take good notes to get by.

    My question is will I run into any issues using a 2924 switch. Since I'm not sure how deep into QOS CCNA Voice goes, will the 2924's limited QOS capabilities be enough to cover the exam's objectives?. Also, will I be limiting myself by using soft phones vs the real thing? I know there is no substitute for the real thing, but from what I've read IP Communicator is pretty close.

    Thanks

    I wouldn't be too concerned about QoS in CCNA-Voice, it only gets 10 pages in the Study Guide and most of that is very basic theory. The only command they look at is auto qos. This probably won't be supported on a 2924xl. I ran into the same problem using a 3524xl-pwr, just had to bypass implementing QoS on the switch, but you can do it on the router.

    The other limitation you are likely to come across with the 2924xl is voice VLAN support. My 3524xl had the commands to implement multi-VLANs as per the Study Guide, but in practice... I had to implement a hybrid solution that worked fine. If you have trouble working it out when you get to that stage, open a new post and I'll share my solution.

    As a PoE/InLine power switch is probably beyond your budget, look for a 2950 switch with Enterprise Image, this should (I don't have one handy) support more features compared to your 2924xl.

    The CIPC will work fine in place of real phones, so no problems there. The only problem I can see, it you'll either need multiple PCs to implement multiple phones, or possibly multiple NICs in one PC. Everything is tied to the MAC address.

    Cheers,
    Dave

    Wow is this fantastic or what??

    I have yet to look into voice but I know there are so many components and one day knew I had to confront them.

    This will really help me out and others.

    For those studying this topic or completed it, would you say that it's the most "fun" topic out of the CCNA security, voice and wireless?

    Voice... fun
    Security... something I'll need to look at, just to broaden my knowledge
    Wireless... as long as I can walk round the house with my laptop then I'm happy

    I just finished my CCNA Security on Thursday. I immediately jumped into the voice Official Cert Guide. The book is written by Jeremy (CBT Nuggets) which means its thus far a lot more interesting than the Security (official cert guide). I'm waaaaaaaaay more engaged in the voice than I was with the security. I enjoyed the security studies... but I could only look at and deal with the SDM for so long before my eyes would begin to bleed and my mind would explode trying to figure out a java error!

    The voice seems alot more fun thus far. I'm still reading through the theory of voice and the foundation of PSTN. I can't wait until I get to the configuration part. Hope this helps!

    There are a lot of questions surrounding recommendations/suggestions for building a CCNA-Voice Lab. No, this won’t be a definitive guide, as there are many possible roads to travel and variations on a theme. But it might give you ideas for what is needed, what the course topology is, what could be added, and what is possible. This configuration is basically what I used, with the exception of the UC-500, to complete the course.

    For those thinking of the CCVP track, I'll try to highlight what can be reused moving on.

    Please treat this as a work in progress, and I hope some find it usefull. I’ll try to update it (and proof read it better) as time goes on.

    For those wanting to build a CCNA-Voice Lab from GNS3, you'll need to look elsewhere, I personally prefer real "touchy", "feely" hardware where I can.

    So you know where I'm coming from...
    Passed my CCNA in December 2007, passed my CCNA-Voice in June 2009. I’m currently studying towards my CCVP (almost completed CVoice) having come from a TDM PBX background and unfortunately am yet to put any of my investment in CCNA/CCNA-Voice knowledge to practical use, so I don't have all the answers. This is basically what I've learnt as I've muddled through it.

    I’ve broken the Lab down into;
    • “Core”, what is essential
    • “Options”, what could be added or would be nice to have
    For all routers and switches, install as much flash/dram as is required (see Cisco Feature Navigator hxxp://www.cisco.com/go/cfn for details), and the more recent the IOS version and hardware platform the better. I’ll also indicate what equipment I used that worked well for me as a base-line.

    See attachment for network topology.

    “Core” Components

    Switch-A
    • acts as a VTP server
    • would suggest 2950/3524 series or later hardware platform
    • I used a 3524
    Switch-B
    • acts as a VTP client
    • supplies access and voice VLANS to IP/Soft Phones
    • would support AutoQoS if possible
    • would suggest 2950/3524 series or later hardware platform and power bricks (CCNA-V), or
    • would suggest 3524-PWR/3550-PWR or later hardware platform (CCNA-V, CCVP)
    • I used a 3524-PWR (this needed some “hybrid” configuration to work, partly from the book, partly from investigation, no AutoQoS)
    DHCP Router
    • acts as a DHCP server (the name gives it away)
    • acts as a NTP server for down-stream devices
    • would suggest 262x/265x or later hardware platform (CCNA-V) with minimum IOS feature set of ipbase
    • would suggest 262x/265x XM series or later hardware platform (CCNA-V, CCVP) with minimum IOS feature set of ipvoice
    • I used a 2691 with adventerprisek9_ivs IOS 12.4T, CME 4.1, Unity Express (allows connection to my home network via fa0/1 and can be used as a gatekeeper for CCVP)
    CME Router A
    • acts as the CME voice gateway
    • should be able to take VIC cards natively, or via a NM voice module
    • needs FXO, FXS ports (CCNA-V), analogue phone(s) [handsfree makes it easier], DSP’s [type depending on router model]
    • optional Unity Express (CCNA-V), can get by without it
    • optional E1/T1 (CCNA-V, CCVP), can get by without it
    • would suggest a 1751/1760 or later hardware platform (CCNA-V) with minimum IOS feature set of ipvoice, as these support VICs natively, can be reused as branch site routers (CCVP)
    • would suggest IOS 12.4T or later
    • would suggest CME 4.1 or later
    • I used a 1760 with adventerprisek9 IOS 12.4T, CME 4.1, WIC-2T, VIC2-4FXO, VIC-4FXS/DID, VWIC-1MFT-E1, PVDM-256K-20
    • while the VG200 supports FXO / FXS / E&M / E1 / T1, it does not support CME. I'd put this into the same category as the MC3810, "a bit long in the tooth"
    Console PC
    I’ve provided an address for where the software is free, or freely available from Cisco with a guest CCO login (yes, you can get some things from Cisco for free). If the links don’t work, just use you’re favourite internet search engine.
    • T.F.T.P App:
      • T.F.T.Pd32 server
        • hxxp://t.f.t.pd32.jounin.net [take out the extra dots]
      • Solarwinds free T.F.T.P server
        • hxxp://www.solarwinds.com
    • Console App:
      • Putty
        • hxxp://www.chiark.greenend.org.uk/~sgtatham/putty
      • mRemote (Putty in a tabbed interface)
        • hxxp://www.mremote.org
      • vRD 2010 (Successor to mRemote, reverts to a limited mode after the 15 day trial, but still good enough for a home lab)
        • hxxp://www.visionapp.com
    • Syslog App:
      • Kiwi Syslog daemon (great for monitoring router/switch activity via SNMP once configured)
        • hxxp://www.solarwinds.com
    • Cisco IP Communicator
    • Optional:
      • Router Config App: (depending on router model)
        • Cisco Security and Device manager
          • hxxp://www.cisco.com/go/sdm
        • Cisco Configuration Professional
          • hxxp://www.cisco.com/go/ccp
      • Cisco Network Assistant (provides simple network management and topology view)
        • hxxp://www.cisco.com/go/cna
      • Cisco Packet Tracer (handy to have anywhere for simple IP testing, its quiet compared to routers)
      • Cisco CME Quick Configuration Tool (hard to find, but nice to have to see how CME configs are made)
    IP Phones
    • minimum 2 x 7940 series, and CIPC. If you are using a powered Switch B, make sure you know the difference between InLine Power (Cisco pre-standard) or PoE (IEEE 802.3af) [I didn't when I started, but was just lucky with my purchases]
    • I used 1 x 7940G, 2 x 7960G, 2 x 7912G, CIPC
    Other materials
    • CCNA Voice Exam Certification Guide
    • CCNA Voice CBT Nuggets
    • Exam Cram CCNA Voice (handy as an alternate source of information)
    • IP Telephony Using Callmanager Express Lab Portfolio
    • Access to Cisco’s site for documentation and another insight into command usage
    ----------8<----------

    Option “A”

    Unity Express

    A moderately expensive item that you can probably get by without for the course and just rely on the Study Guide and the CBT. I always like to have hardware to play with so went hunting on eBay. Make sure if you do get one it comes with the CUE software installed. I took a punt and bought the lowest cost one I could find, that had had the HDD wiped. So had to go searching for the software, fortunately...

    The study material indicated that there are 2 ways to re-install the software, but these make the assumption that software also pre-exists on the HDD. If you do buy a wiped one (and save money) there is a 3rd method found in the CUE installation docs which involved using the boot loader. Think of this as the CUE equivalent of a routers boot ROM. If you need this info, just PM me and I'll pass it on.

    There are a few variants of CUE and depending on your router model will determine which one(s) could be right for you.

    hxxp://www.cisco.com/en/US/docs/voice_ip_comm/unity_exp/compatibility/cuecomp.htm

    ----------8<----------

    Option “B”

    Home Network Connection

    Not really required, but very handy for time synchronisation to an external NTP source, and saves doing a set clock on multiple devices. Public NTP servers can be found at;

    hxxp://support.ntp.org/bin/view/Servers/NTPPoolServers

    It'll also be handy to know where to find these if you move on to CCVP. Don't be supprised if it takes 10 minutes or more for your devices to sync to the correct time, it bugged me for a while. If you're using a syslog server to capture all of your output instead of using the console, it's easier to have all your devices, both routers and switches synchronised to the same time source.

    ----------8<----------

    Option “C”

    Remote Site

    To be able to test your VoIP dial-peers it's handy to have second site setup. This can be as simple or as complex as you like, I used a 1760 configured similar to the core site, but without any VIC's, running CIPC and connected via DTE-DCE cable. This allows you to make simple test calls in both directions.

    ----------8<----------

    Option “D”

    UC-500/520

    OK, there's no easy way to say this, it's a big ticket item. Cheapest I've seen is about AU$3000 for the wireless model, without handsets.

    On the plus side, it has almost everything for the SO/HO in one box, DHCP, PoE, FXO/FXS, CME/CUE.

    It has it's own GUI and configuration manager;
    • Cisco Configuration Assistant
      • hxxp://www.cisco.com/go/cca
    When I did the exam, it was based on v1.8 (give or take) of CCA, CCA is now at v2.2.1 and has changed a lot. So it would be handy to know both.

    For those that can't afford one of these to practice on (and I'm one), print out the screen shots of each tab of the interface and set yourself some scenarios (set up 2 phones, with voicemail, maybe a hunt group too). Unfortunately this won't give you the answers, but it will get you familiar with the interface.

    ----------8<----------

    If there is interest out there, I'll set up a shared folder on 4shared with the Apps and any docs I can think might be usefull. With the moderators permission that is, I don't want to break any rules.

    ----------8<----------

    General Info:

    VIC's and second generation VIC2's are Voice Interface Cards supporting analogue connections for;
    • FXO (to the local telephone exchange)
    • FXS (to an analogue phone)
    • E&M (to a PBX)
    VWIC's and second generation VWIC2's are Voice/WAN Interface Card supporting digital connections for;
    • E1 services for either Voice or Data (The Real World )
    • T1 services for either Voice or Data (North America and a few other places)
    ----------8<----------

    Changes:

    15-Apr-2010: Added Option C (finally )
    20-Jan-2010: General Info section, and MC3810/VG200 info added
    15-Jan-2010: Added Options A and B
    28-Dec-2009: Relabeled options, updated network diagram, added UC-500 section, added mRemote to Apps
    21-Dec-2009: Initial draft
    HI, Thx for this great posting, what did u use to design the network topology?

    Ouch; this is starting to look expensive. I've the 2 2950 switches and a 2610XM router I just bought. A couple 2610's but not sure if they'll be at all useful here. Those 7940 IP phones look pricey too. Any suggestions on where it's possible to shave a bit off?

    For testing, I use IP communicator [Softphone]. Softphones can do some of what a hardware phone can do as far as testing your dial plan, calling via PSTN or to other "sites" [another CME install across a serial link].

    Hi robert@uk,

    Sorry for the delay in getting back to you, I've had really limited internet access these past 2 weeks. The network diagram was done with Visio, the Cisco symbols came from the Cisco web site. You'd need to do a search for exactly where.

    I haven't taken the exam yet but I like the material in the CCNAV a lot better than the CCNAS stuff.. I dunno why.. maybe cause I've never played with voice stuff before and it is quite exciting to get that first phone call going with a CME router and a couple of phones Plus JeremyC from CBT Nuggets gets you really pumped for this voice stuff!

    Hi

    just a question, I bought 2811 router from ebay, I plan to play with voicemail, what do I need for this? I saw that there is an option for AIM-CUE and I saw one in ebay selling a cheap Cisco AIM-CUE-1GBCF 1GB Compact Flash. Do I only need the 1GBCF for me to practice voicemail in my 2811? How about the AIM card itself where the 1GBCF card will be placed? Does it already included in the 2811 by default? Or I need to buy it separately? I ask this because my 2811 is just on its way and this is my first time to have a cisco router,

    thanks!

    You only need to post once. I've answered your questions already in your other thread.

    Default LAB Equipment

    Hi Azaghul,

    short question, i`m a little bit confused. I have the following Hardware:

    4x 2950 Switches
    1x 2970 Switch
    2x 2610 XM Router (First with WIC1T and a free slot and second with WIC1B S/T and WIC2T)
    1x 1721 Router with WIC1T
    1x 836 Router

    1x CUCM 7

    Do i need only some IP Phones (cisco 7940?) and FXO/FXSs (where could i buy thos cards and how many?)and than my CCNA-V/CCVP Lab is complete ? Which IOS should i use for the differnt routers ?
    With this hardware what lab would you create? First i want start with the exam 642-436 CVOICE and than go on with the other CCVP exams.

    Looking forward to read from you.

    Regards
    woisch

    You don't need FXO/FXS cards unless you want to

    a. connect your lab to the telco
    b. connect a regular phone to your lab

    7940's are a good phone choice, that's what I use.

    Since you have a CUCM server, the IOS on your routers isn't a big factor. If you wanted to use a router to do CME, that's another story.

    Switch config is what is important here, as is (obviously) your CUCM config.

    Not sure if a 2970 has all the QoS features you need. I use a 3550.

    Thanks Netwurk.
    So i thing for the beginning i do not need FXO/FXS cards.
    So the LAB equipment is adequate do you think?

    Could you give me an example for a maybe LAB? I`m very new to this voice stuff.

    And what do you think about CUCM and CME.... what is a real life scenario?

    Here's a good home lab example

    CCVP: Building a Home Lab | NetworkWorld.com Community

    In real life, most firms use CM or CUCM. CME is suitable for a small business.

    Do you have a switch than can do PoE? If not, make sure you get AC adapters for your IP phones.

    EDIT - As was mentioned earlier, you can also use Cisco IP Communicator on a PC instead of getting IP phones

    There are alot of blogs out there with introductory voice labs if you spend some time on google. CUCM is big business, and CME is small business. What I suggest to people is to learn the fundamentals with CME, as it is much easier to set up and get phones ringing in. I'm currently diving into the enterprise world of voice, and it is easy to overlook the little things you should know. CUCM can handle thousands of phones (30,000 per cluster, if I remember correctly), where CME caps at around 250 depending on your equipment.

    If you want something you can sit down from scratch every day and lab with, go with CME. If you want a lab that you build up slowly peice by peice and have an amazing enterprise network at the end of a few days of work, go with CUCM.

    Again to start with, I suggest CME, since it is easier to just sit down and figure stuff out from scratch. Much better for the learning process.

    For CME, I'm using an Advanced IP Services image on a 2691. There are also voice images if you are low on flash.

    is 12.4 good or do i need 12.4T ? The advanced ip services with 12.4 needs 128 DRAM and 32Flash. Thats what i have.

    12.4T needs more.

    Whats the big difference between 12.4 and 12.4T ?

    They mention it has improved voice quality, but I wouldn't think that's a big deal in a lab. Of course, I'm not an expert on IOS releases - research the Cisco site for details.

    Agreed, I'm pretty sure I labbed up on 12.4T however you should try and configure some phones to ring and see if it works. If it does, no need to spend more money.

    Is CME 3.2 suitable or do i need a newer one? Is it right that i could use only CME 3.2 on a 2610 XM ? I`m confused if i go through the Feature Navigator.

    CME 7 is only availabe on other routers right ?
