Collaboration is Hot … Bringing Productivity Services and Apps into the Enterprise

As you all know, Cisco has defined collaboration as four key pillars:  Social, Mobile, Visual (Video) and Virtual. We all have been experiencing these pillars – each one of them is critical and is moving into the enterprise. And what is particularly exciting is their convergence and rate of speed. Read More »

Contact Center SIP Trunks Part 2 — Reducing Costs and Improving Call Control for Outsourced Contact Centers – Future Directions

In my  first blog I described how Cisco IT is interconnecting our outsourced Contact Centers using SIP trunks, replacing the more costly (and less effective) PSTN trunks.  In our first round of SIP trunk deployments we expect to save almost 25% of our current contact center calling costs (or $2M per year).  But there were other, less tangible benefits as well.

Contact Center SIP Trunks Part 1 — Reducing Costs and Improving Call Control for Outsourced Contact Centers Today

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.

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.
