With some recent troubleshooting, there was a need to capture packets off a Cisco ISR. Walking through the steps is small effort, however there are some some notes that can aid with the configuration.
I recently was having a discussion with a peer around Collaboration, the Spark to Webex updates, and how it has changed overtime. A bit of reminiscence from previous versions of the Collaboration strategies and where they are going prompted me to create this entry. Lets take a look at Collaboration’s past, present, and future and assess how your organization has adopted.
Working through many conversations with customers has lead to example the steps required to complete some Microsoft and Cisco integrations within the Unified Communications (UC) space. For the scope of this exercise, the Skype for Business and Jabber endpoints using the same domain will be enabled for direct messaging only communication. This is the first post in an intended mini-series referencing the integration as well as user experiences.
With the recent release of Cisco UC products, an additional feature has been delivered. Jabber messages, both internal and Mobile and Remote Access (MRA) connected, can now be delivered through Apples cloud-based Push Notification Service. While this may not peak everyones interest, it is a prelude to enabling the same functionality for other communication channels.
After completing an upgrade to Expressway 8.8.1, it was noticed that Mobile and Remote Access (MRA) suddenly stopped working. After some searching and log files, it was found to be a DNS PTR record issue. The implemented “feature” that required the Expressway-E DNS PTR resolution had only been implemented as a requirement in version 8.8.1.
With the release of OpenSSH v6.7, weaker ciphers have been disabled. Cisco CUCM has not updated the weaker ciphers used within CUCM as of v11. This causes issues with backups to the OpenSSH versions in the latest distributions. This post walks through the identification of the issue and the correction used in the CollabBackups appliance.
I currently have some UC 10.x and 11.x licensing that is purchased and used for demonstrations. With the recent purchase of the 11.x licenses, a Prime License Manager (PLM) server was stood up to manage the multiple clusters using multiple versions of the CUCM platform. This post walks through the process of standing up a stand-alone PLM server, pulling licenses from the Cisco licensing website, and the rehosting of licenses from a legacy license manager.
Looking to increase the switching capabilities within my setup to support the Gigabit needs of my ever growing environment, I ran across a spare 4507E chassis and some line cards. With the new platform came the opportunity to research and apply the latest QoS configurations available.
I was working through a factory reset process on my Cisco 8945 phone and after the reset completed successfully, the phone attempted to download the latest firmware version from the device defaults page. The phone froze after powering on each time. Like usual, the fix was pretty straight forward.
I had been experiencing slower than usual downloads over Time Warner’s network and it had become unbearable when I could no longer support a G711 call. For once though, it was not Time Warner’s fault.
