    Cisco 7961 and 7960 vs Cisco 7970G

    The CCIE Voice lab say to use Cisco 7961 and 7960 phones
    Does it matter if I use all Cisco 7970? I already brought 6 of them and thinking of buying more Cisco 7970G
    I know the Lab is getting upgrade soon, can someone recommend next model that might be used to next version of the lab?

    Re: Cisco 7961 and 7960 vs Cisco 7970G

    The CCIE lab currently use 7965 phones which are effectivly the same as the 7962 but with a colour screen. The 7961 are also the same except for the colour screen and they dont support wide band without an upgrade but thats no issue really. So 7961, 7962 and 7965 are all good choices for the lab.

    The 7960 does not support some of the features you will need for the CCIE voice (its a ver 2 phone where as the 7961 2 and 5 are ver 3). Im not totally sure (without looking it up) about the 7970 as this does have more memory but this is a ver 2 phone also.

    For my home lab im using a mixture of 7961, 7962 and 7965 for the 3 sites and a 7970 as my PSTN phne.

    Re: Cisco 7961 and 7960 vs Cisco 7970G

    I already brought 6 of the Cisco 7970 because i thought it was better model because of higher number.
    The pdf said it's ok to substitute to 7970.
    I want to have the correct phones for the home lab.

    How many of each of the Cisco 7961, 7962 and 7965 should I have for my home lab?
    We are suppose to have total 12 phones for home lab?

    I can't get 7961 because they are not sold much new except on ebay
    Should I get 4 of 7962G and 2 of cisco 7965 ? 

    For the CCIE Voice lab we need total 12 IP phones?

    Six phones should be enough going by this statement in the INE rack rental specifications "The INE Voice Racks are built to support all the features and technology used in the actual CCIE lab exam ".

    You always have the option of adding a CIPC softphone if you need one more, possibly for the PSTN. If  preparing using the INE workbooks, you really would not find a task where you need more than 6 phones. You definitely do not need 12 phones except you have personal reasons.

    Re: Cisco 7961 and 7960 vs Cisco 7970G

    Oh I get it, your 6 hardware phones are sufficient. You do not have to worry about the other six phones. They are physically attached to the racks at INE location. If you are connecting using the VPN-less method, then those are the phones you would try to control via http. 

    When you connect via VPN and perform 'show cdp' or take a look at the config on any of the switches, your phones are the ones connected via VPN to interfaces fa0/10 and fa0/11(CorpHQ & Branch 2), fa0/1/3(Branch1). The INE phones are connected to ports fa0/2, fa0/3 and fa0/4(PSTN). 

    The rack rental guide explains the connection details.

     

    Cheers!

    Re: Cisco 7961 and 7960 vs Cisco 7970G

    I made the mistake of buying 6 of Cisco 7970 based on the pdf
    I was told that I need 7961 / 7961 / 7965 for the lab features
    Can you recommend how many phones i should get for each model?

    Re: Cisco 7961 and 7960 vs Cisco 7970G

    If all you need to do is practice for the lab and you want a complete set of phones, I would recommend the following options

    1. 5 7961's and 1 of any other phone with more than 6 line buttons for PSTN (CIPC, 7970, ...).  OR
    2. 5 7962's and 1 of any other phone with more than 6 line buttons for PSTN (CIPC, 7970, ...).  OR
    3. 5 7965's and 1 of any other phone with more than 6 line buttons for PSTN (CIPC, 7970, ...).   
    You can of course mix them to your preference if you happen to get less than 5 7961's for example, substitute with the next higher model available. I have not tried a 7965, but from looking at the datasheet, you will not run into any technical issues replacing it with the 7961. The advantage of the 7961s is cost savings. For my practice, I use four 7961's (got off ebay in very good condition) and CIPC for PSTN because it has 8 line buttons. 

    These are great for study if you are working towards taking v3 exam. However, I hear v4 should be announced soon and I do not know if anyone knows the phone models it would contain. If you do not intend to take your lab before the year runs out, you might want to do some more investigation before purchasing to be on the safe side both technically and financially.

    Re: Cisco 7961 and 7960 vs Cisco 7970G

    I agree having 5 x 7961 is probably the best bet, this way you dont need to mess around editing the CUCM tar files and asoicated phone templates for each lab. All you need to do is change the mac's of your phone devices once imported. I have a mixture of 7961 7962 and 7965 so this is a bit of a pain. As for the change in the lab to v4 im racing to take a first atempt in May and hope to fit 1 or 2 atempts after that if I cant get it 1st/2nd time but time will be tight if i believe what I hear about an iminant change

    S.Wright,

    Best wishes to you towards your exam.

    I am also working towards my first attempt in May - Toronto Mobile Lab. How is it going with the Workbook 2 Labs? I find it challenging striking a balance between mastering the technologies and finishing the lab in 8hrs. Sometimes my 8.5hr rack rental/study time is up and I still have unfinished tasks, particularly those towards the end like CUPS, UCCX and QoS!

    James,

     

    I am using 7 7970G phones and I am able to test all the features in the current blueprint, so don't worry. I am not sure if they will support all the new features in the new blurprint though.

    Re: Cisco 7961 and 7960 vs Cisco 7970G

    I am also facing the same challenge. I went in last December for my first attempt and I didn't pass. I think I would have passed If I had more time. I didn't have time to finish some tasks and to review the other tasks. Currently, I am able to do most of the stuff in the blueprint but I need to work on my speed.

     

    My second attempt is in May and I am working towards finishing the lab in 6 or 7 hours and then checking and reviewing my configuration.

     

    Good Luck.

    So 7979G is fine for my CCIE lab. i read the PDF from INE that I can use 7970G but so many people told me I can't use 7979G
