How Cisco is Using SIP Trunks to Reduce Calling Costs

Like many large enterprises, Cisco makes a lot of phone calls.  Cisco previously used a lot of TDM trunks from multiple carriers to carry thousands of voice calls from our North American Cisco offices to the PSTN. The problem is, we had over 100 TDM trunks we were paying for every month, to carry our voice calls for these sites.  Four years ago we started looking around for a more cost-effective and manageable way to support all these calls.  After a good deal of searching, screening vendors and testing, we finally found it, using Session Initiation Protocol (SIP) trunking technology.

For the Cisco campuses in San Jose and Research Triangle Park (RTP), we will replace over a hundred PRI (23 channel) TDM trunks, used for long-distance voice calls for all of our North American sites, with SIP trunks.  The new San Jose link is a 250 Mbps SIP trunk carved out of a 10 Gigabit Ethernet WAN access line, while the RTP link is a 20 Mbps SIP trunk carved out of a 45 Mbps DS3 WAN access line. Together, these SIP trunks give us the capacity to carry over 2400 concurrent calls and a total voice call volume of 2 million minutes per month.

Cisco gains more business value by migrating Web 2.0 tools to the Cisco Quad platform

January 27, 2012 at 9:00 am PST

We recently published a new case study that describes how Cisco IT has evolved its internal collaboration and social sharing site, called the Integrated Workforce Experience (IWE). With IWE and the Cisco® Quad™ platform, Cisco IT provides the types of social networking tools—blogs, microblog messages, and informal videos—that employees use outside of work. In IWE, those tools are optimized for internal use within Cisco and are implemented in a robust, scalable, and secure way. Originally created by Cisco IT on an open-source platform, IWE now runs on the Cisco Quad platform. The platform migration required integrating the social sharing tools with minimal user disruption, preserving user documents, migrating different user data types appropriately, supporting application portals, and educating employees.

Collaboration is Hot … A “Bring Your Own Device” Mobility Update

Cisco kicked off the New Year with a significant milestone:  we’ve reached over 50,000 users of personal mobile devices in the enterprise. In fact, while we’ve seen an upward trajectory of personal devices over the past two years, the major growth spurt was in the last calendar year – our total mobile device count grew 52% in 12 months. And no surprise:  this was primarily seen in Apple devices. Read More »

Pruning Your Community Garden: an Approach to Community Lifecycle Management (Part 2)

Part 1 of this blog series established that community administrators and owners need a way to assess and manage their respective community gardens and prune away communities that are no longer useful; see http://blogs.cisco.com/ciscoit/pruning-your-community-garden-an-approach-to-community-lifecycle-management-part-1/).  This blog describes the primary tool that will be leveraged by community administrators and owners within Cisco’s Integrated Workforce Experience (IWE) to view and tend to their respective community gardens.  The tool is called the Community Lifecycle Management Portlet (LCMP).  The LCMP represents one of several components that have been developed – in a partnership between Cisco IT and the Collaboration Business Technologies organization – as an extension of Cisco’s Enterprise Collaboration Platform (Quad) to maintain the overall health of our community ecosystem.
