Quick video warming up, ready to finish the UCCX series video on 10.6 - so I needed a way to test calling from my home phone to my lab
The Video The Content Just basic troubleshooting of a call from UC520 to CUCM using SIP protocol
What to look forward to? Not much really on this one, just getting ready to additional videos and testing - enjoy!

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.
Hi there, Here is the link to the CUBE Third-Party Interoperability Fax Guidelines - http://www.cisco.com/c/en/us/support/docs/voice/t38/116280-configure-cube-00.html I decided to copy the Source code of the page just not mess around with the contents and images which help on understanding the Fax protocols with Cisco CUBE.
Also this makes it a nice link to keep in your toolbox.

I promise this will be a very short one. This week I purchased 3 9971 with the camera in order to get ready for my rack rentals for CCIE Collaboration, well when I got them I noticed that the phones belonged to someone else(Duhhh!!).
I needed to do a factory reset on those guys, or at least be able to remove the ITL files.
My problem was that I could not do any of these because the Admin Settings was locked by a password. Of course you can remove this password but if only if your phone is able to get the SEP config from your CME (off course if you are using CME) - TCLSH procedure here http://collabengineer.com/2014/11/15/cisco-sip-phones-admin-password-removal-cme-tclsh-operation/
On this one I wanted to share a really nice way to remove the Admin password from Cisco SIP phones.
It really is annoying to type the Admin password every time you need to modify or at least take a look at the configuration on your phone.
As you may know when you configure a SIP phone on CME you need to give it a username and password, also SIP is kind enough to publish the SEPXXXXX.cnf.xml file to Flash
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!
Cisco Live 2014 – San Francisco
Just wanted to take this time to talk about my experience at Cisco Live 2014, representing the Modcomp team.
It was a great experience and a nice way to meet with people that is in the same boat you are, Engineers that are seeing the same issues you see and others that have it all figured out (You want to be like them!!).
So just to get you started off the narration of this adventure, I wanted to start by adding few things that I think deserve to be mentioned:
I was just reading the following Article and wanted to add few things that helped me solve my issue:

*** bearer-cap speech *** This simple command also fixed an issue I had with Jabber clients calling from Softphone mode to cellphones, and they were getting straight to the voice mail of that particular cellphone.
At first it looks like a simple issue with the phone company, but then you start re-thinking it because it happens with every cellphone you make and with every SIP device you have connected to CUCM.
Hi there, so today I wanted to bring up something that was very confusing to me long time ago. The concept of MGCP, H.323 and SIP.
these 3 are very big and there is a lot of information about them, I just want to explain with my own words what every single protocol means for me and the way I had to put it in my head before I was able to understand the technology behind it.
