Last week we had a RAID Controller fail one of our Cisco C200 UCS servers.  It happens.  For us it seemed to be just a mere annoyance at first, it took down two of our CUCM subscribers and our TFTP server.  Phones failed over to anothe subscriber and our DR TFTP started serving up TFTP [...]

UCCX 8 “Bug” to Watch Out For…

Posted: 20th March 2011 by Rob in Cisco, Uncategorized

CSCtk35441 Bug Details basically states “Dont use admin account names that start with “UCCX”. From the 7.0.1 days our uccx admin account was….uccxadmin.

CCIE Written exam = PASSED!

Posted: 20th July 2010 by Rob in Cisco, Uncategorized

I passed the voice written this morning and I am relieved that piece is over with now. Lots of work/study to do before the lab but I plan on taking that in the spring of 2011.

On my CUCM and Unity Connection clusters at work I uploaded 8.0.2 code for an upgrade that I will execute this weekend. It’s exciting because 1. I will get to play with some new software that has a lot of nice feature (can you say SAF? I knew that you could!) and 2. because it [...]
