Cisco IP Phone Certificates and Secure Communications

Securing Cisco IP phone communications is important that helps organizations protect trade secrets and facilitate business and compliance requirements. Cisco IP phones support secure communication for both control and data channels. The security that is incorporated into Cisco IP phones includes the encryption and authentication of signaling communications between the Cisco IP phones and the Cisco Unified Communications Manager. Moreover, Cisco Unified Communications Manager supports encryption, authentication, and anti-replay protection of the voice packets that are exchanged between Cisco IP phones.

Keeping Oversea Relationships Close through VoIP and Social Media

By Kristen Vargas, Guest Columnist

Before the emergence of second generation providers such as Skype, I was always a firm believer that face-to-face contact and physical interaction were essential to sustaining healthy relationships. Born and raised in California with most of my family and friends living in the same general vicinity, I grew accustomed to the comfort and convenience of having them nearby.

However, unpredictable life events followed, and I found myself building a life with someone serving in the U.S. Air Force. A natural consequence of this newfound military life meant that I inevitably was going to be moving from base to base to follow my husband as he served his term. The idea of leaving California to live at my first base in Idaho, although temporarily, was a move I was not altogether excited about and left me feeling a bit apprehensive about living in another state for the first time.

Cisco Experts to Give Breakout Session on Mobility and Virtualization Security at Government EventThis Week

Two of Cisco’s finest will be presenting a breakout session today, April 2 at the 2012 Department of Defense Intelligence Information Systems (DoDIIS) Worldwide Conference in Denver, Colorado.

Mike Harttree, Technical Solutions Architect, and Gary Hall, Chief Technology Architect, will present “Survey of Wireless & Mobility Architectures for Communication and Collaboration,” from 3:20 p.m. to 4:05 p.m.

Mobile and wireless technologies are transforming the way the world works. Personal and corporate mobile applications enable individuals to collaborate in new ways to improve their productivity. One of the great myths in the Intelligence Community and Department of Defense is that security concerns prevent wireless technologies and mobile devices from being used in support of a mission. The reality is that the wireless infrastructure is already in place and is expanding rapidly throughout the DoD community. How this infrastructure is integrated into enterprise and mission architectures is the key to successfully deploying more wireless capabilities and protecting information such as classified data, when it is transmitted over a wireless medium.

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.
