Cisco has partnered with several outsourced vendors over the years for initial handling of many front-line calls and general information inquiries. Connecting these vendor environments into a single Cisco customer contact environment is critical for good customer care, but costly and not always easy. However, early this year we made a change: we’re using SIP trunking and Cisco Unified Border Element to bring us much closer together, and save money into the bargain.
Contact Center SIP Trunks Part 1 — Reducing Costs and Improving Call Control for Outsourced Contact Centers Today
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.

As noted in my last blog, Cisco is continuing to see an explosion of personal smart phones and tablets coming into the enterprise, with now more than 50,000 personal devices in use. Additionally, employees want to do more and more on their phones with new applications. That’s not surprising – there is a massive burst of killer apps! Read More »
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.

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 »
