Changing CUCM hostnames to FQDN hostnames

CUCM-LogoI recently ran into a scenario that wasn’t really covered in Cisco’s Changing IP Address and Hostname for Cisco Unified Communications Manager documentation. We had already had our CUCM hostnames defined by hostname, but they were not using Fully Qualified Domain Name (FQDN) hostnames. In this post I will cover the steps I used to just add the domain name to my node definitions as the process is much less complicated when compared to the full rename procedure.

Fix existing RTMT profile after CUCM node rename

RTMT-IconI recently did a migration to move our CUCM nodes to be specified by FQDN hostname. We had been using non-FQDN hostnames, however, we wanted to migrate to using the FQDN hostname to line up with current best practices and in prep for piloting Mobile and Remote Access (MRA) on Expressway. In the process of putting together my implementation plan, I realized that we would likely lose any RTMT profiles we had saved which can be quite complicated and have a number of custom counters defined.

Cisco 7900 series 9.4(2)SR1 headset hell

IPPhoneFew things in collaboration will get people more worked up than a user experience change, especially when a contact center is involved. (Protip: do NOT anger the contact center gods). Here is a little story about firmware release 9.4(2SR1.1) (or 9-4-2SR1-1S or 9.4(2)SR1 depending on where you see the version referenced) for the Cisco 7900 series IP Phones and how it has caused grief for not only us, but other customers as well.

Installing 3rd Party Certificate on Cisco Prime License Manager

As part of the 10.X Cisco Collaboration Systems Release, Enterprise License Manager (ELM) has been changed to Prime License Manager (PLM) and the system operates a little bit differently than ELM did. There are a few differences including how you install 3rd party signed certificates on the box. I will discuss some operating differences and how to handle getting 3rd party certificates on the PLM.

Cisco Live 2014 CAE Bands

Wow! Just got word that the bands for the Cisco Live 2014 Customer Appreciation Event (CAE) will be Lenny Kravitz & Imagine Dragons at the home of World Series Champions – The San Francisco Giants!

Personally, I think this is huge! I have been to lots of Cisco Live CAE’s and I think as far as bands go, Imagine Dragons is one of their best picks to date! I am so disappointed I can’t go this year, but if you’ve never been, this would be an great year to go to check it out! Read more after the jump.

Unable to install Cisco UCCE 9 Maintenance Release

Background: Over the past 6-9 months we have been planning for our Technology Refresh migration from Cisco Unified Contact Center Enterprise version 8.5 to version 9.0. This is both an upgrade and a hardware refresh to virtualized servers. The upgrade is being done to maintain software currency (in the Cisco Collaboration application space you should always know when your next upgrade is planned) as well as allow us to upgrade our CUCM cluster to version 9.X. We also want to eliminate our legacy Cisco MCS servers and migrate everything to virtual servers. Continue reading Unable to install Cisco UCCE 9 Maintenance Release
