With the drive of unified communications to cloud based connectivity, a Session Border Controller (SBC) can play an important part in supporting a migration from premise equipment. Some gateway manufactures provide a convenient Graphical User Interface (GUI), others still focus on leveraging a command line interface (CLI). This overview will step through the generation and signing of the certificates that would be used for Tranport Layer Security (TLS) for both signaling and media within a Cisco Unified Border Element (CUBE).
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.
While working through Intradomain Federation efforts, there was some issues with the Skype for Business client querying the users associated to the domain, but on a Cisco IM & Presence platform. After making a simple change and clearing the clients local cache, we were able to query the remote users.
It was noticed that the disk space was low on Exchange 2016 when one of my on premises mailboxes was not receiving email. A few searches lead to the need to setup Exchange aware backups on the Windows Server 2012. This post covers the steps taken to free the space.
It has been a while since my environments vCenter appliance has been upgraded and it was time for a refresh. After acquiring the media and keys from your VMware portal, the steps below outline the process that was taken to migrate a vCenter Appliance v5.5.0 to 6.5.
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.
With the requirement to demonstrate a Skype for Business audio integration with a CUCM, it was decided to integrate within my system. Standing up a Skype for Business server to provide Enterprise Voice was not overly complex, but certainly presented more than one unique method to implement specific features. One of those features proved to be creating a SIP trunk using TCP instead of TLS.
