Passing the CCIE Collaboration Lab was really hard and a very nice and entertaining experience, which I feel very happy to say that I completed the challenge!!
I will be very short on this post and will make it technical and a bit emotional for the people out there that may benefit from it at all
How many times is enough? Well I started this year thinking that it was going to take as many times as it needed to take… Financially this could be brutal and indeed it is. But the reality is that you need to make everything possible to make it happen. Just make sure you will get it, no matter what! and put every effort possible to achieve the goal.
We are UC/Collaboration guys and if you are like me, Exchange 2013 is not your expertise… but if you are handy with Exchange 2013 that is great, and maybe you can use the following post useful too.
Single Inbox Unity Connection 9.x Exchange 2013
Here are some useful links that I have found in order to get Single Inbox configured:
This is the main link:

High level and pretty much what you need to do in order to complete the configuration:
Yes, another upgrade and more with it. This one was very special and I was totally blaming myself after the TAC engineer helped me figure it out.
I was always told, or I remember it was good practice to always get the latest Upgrade file from CCO Downloads page for everything. Well I did that and found myself into an issue.
The scenario:
Customer Upgrading CUCM, CUC and IM&P servers from 9.1.2 to Version 10.5 (No issue here):
So with the introduction of Cisco Prime Collaboration Deployment, now upgrade any of your UC applications its easier and quicker than before. One of the big advantages that I see with this new product is that the product can have control of the overall infrastructure, starting from VMware all the way to the UC applications.
For a better understanding of this product you can use the following link: (http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/pcdadmin/10_0_1/CUCM_BK_U9C58CB1_00_pcd-administration-guide-1001.html) - The previous is the one for version 10.x – I don’t see too many changes from version to version.
This one was a very funny one and I’d like to share with you. After an install of a remote office using the following equipment:
CIsco 2901 with an ISM for CUE and an AutoAttendant that when the office is open sends the call to a Hunt Group in CUCM and when they are close the **AA (**prompts) really kicks in. Nothing too crazy right?
After 1 month of the installation received a call that when someone calls the main number they hear not ring back (only death air) until someone answers the call. After this one I had few things to look at but I knew this was a cosmetic issue.
In order to organize myself for my lab preparation I need to work on my speed and accuracy, so I created quick and very general Lab outlines, which will be covering CUCM as of now. I created them so that I can guide myself and know where to begin, where to stop and don’t burn myself (hoping this strategy to work!!)
I know I’m missing lots and lots of information and study domains, such as QoS and yes, QoS… Infrastructure and Multicast… I do feel confident with the Network infrastructure configuration, but need more work on QoS and Multicast, if you know of good QoS labs let me know… enjoy!
Just for curiosity, I would like to know how is the people on this group preparing for the CCIE Collaboraiton Lab, right now here is my preparation and roadmap:
I have completed a lab in order to be able to study most of the technologies included in the blueprint, here is what I have:
3 Cisco 2811 64 PVDM2 1 Cisco 2821 128 PVDM2 1 Cisco 3750G 24 Port 1 Poweredge 1950 III 32GB - 2 TB HD - 2 XeonQuadCore E5240 2.4Ghz 5 Cisco 7961 2 Cisco 7965
Hi there, today I have a customer that wanted to upgrade from CUCM 9.1.2 to 10.5 - which sounds pretty easy… think again, so this is a BE6K deployment where CUCM instance was configured with the recommended OVA from CCO. When starting the upgrade I found that the upgrade didn’t wanted to proceed as expected. and I was getting the following error:
Installation of UCSInstall_UCOS_10.5.1.10000-7.sgn.iso failed
An error has occured but no messages are available. This can happen when another administrator is working on the system at the same time and triggers an error.
