CiscoThanks to affordable IP endpoints in the Cisco 6900 Unified IP phone series more organizations can now take advantage of IP communications. Telephone Magic Inc. is an online leader in providing replacement and spare Cisco IP phones at wholesale prices.

Jeff Jackson, president of Telephone Magic indicates “When our clients call for Cisco IP endpoints we offer a wide spectrum of phones to suite a variety of budgets and Voice over IP network needs. Unlike anonymous shopping cart websites that can have out of date prices, we offer clients a personal relationship with a representative they get to know. We consult them to narrow their requirements and provide current wholesale pricing.”

Mr. Jackson continues, “Most of the Cisco 6900 IP phone models support full-duplex speakerphones for a more productive, more flexible, and easier-to-use IP phone experience. Some models also introduce support for single-call per-line appearance, which offers a traditional telephone interaction for business clients who seek this type of call experience for their staff. Fixed keys for hold, transfer, and conference along with tri-color LED line and feature keys also make the phone easier and simpler to use.”

There are six models available in the Cisco 6900 IP phone series. The Cisco 6901 IP phone is a trimline telephone; the Cisco 6911 IP phone is a one-line VoIP telephone; the Cisco 6921 Unified IP phone is a two-line terminal; the Cisco 6941 IP phone 6941 is a four-line VoIP telephone; the Cisco 6945 IP phone is also a four-line desk phone; and the Cisco 6961 IP phone is a robust twelve-line VoIP telephone set.


Dish Network values its offer at $7 a share, including $4.76 in cash and the remainder in its shares. The offer is 12.5 percent above Sprint Nextel’s closing share price on Friday.
“The Dish proposal clearly presents Sprint shareholders with a superior alternative to the pending SoftBank proposal,” Mr. Ergen said in a statement.

Mr. Ergen said a “Dish/Sprint merger will create the only company that can offer customers a convenient, fully integrated, nationwide bundle of in- and out-of-home video, broadband and voice services.”

Dish Network said it would be able to combine its existing broadband and TV offerings with Sprint Nextel’s cellphone operations, allowing it to better compete with rivals like Verizon that are moving into new areas in search of revenue.

Dish Network’s effort to take over Sprint is the latest of many moves toward consolidation in the highly competitive broadband industry. In 2011, AT&T tried to buy its rival T-Mobile USA, a move that was blocked by the Justice Department because of antitrust concerns. Last year, Verizon scored a deal with a group of cable companies that agreed to sell it spectrum licenses to build its wireless network in exchange for allowing them to sell their cable services inside Verizon stores.


3. Political mandate

In the face of the 2010 post-election riots in Iran, the government there shut down the Internet for 45 minutes, presumably to set up filtering of YouTube, Twitter and other sites. Egypt did the same during its revolution of early 2011. China is actively pursuing the capability to shut down its own Internet this way.But it’s not just countries like Iran and China that think about this kind of control over the Web. On June 24, 2010, a Homeland Security committee in the U.S. Senate approved a bill giving the president authority to wield an “Internet kill switch.” The bill, Protecting Cyberspace as a National Asset Act (PCNAA), proposed to give the president “emergency authority to shut down private sector or government networks in the event of a cyber attack capable of causing massive damage or loss of life.”The “kill switch” provision was removed from the version of the cybersecurity bill that’s before the current Congress.
It’s probably just as well. Almost unanimously, Internet security analysts feel that shutting down the Web would inevitably do more harm than good, given our predicted level of dependency on it in time of war for news, communication with loved ones and crisis information aggregation.
Security guru Bruce Schneier identifies at least 3 problems with the shutdown idea. First, the hope of building an electronic line of fortifications is flawed because there will always be hundreds of ways for enemies to get around it. No nation or legal decree can plug all the holes.
The second major problem is that we will be entirely unable to predict the effects of such an attempted shutdown. As Schneier puts it: “The Internet is the most complex machine mankind has ever built and shutting down portions of it would have all sorts of unforeseen ancillary effects.”
The third major problem is the security hole it exposes. Once a domestic Internet kill switch has been built, why would a cyberattacker concentrate his efforts on anything else?
Given that the number of people who could use the Internet for good in a crisis situation will presumably outnumber the bad guys, it is probably best to not cut off our heavy dependence on the Web just as things are going bad. Given that a recent survey by Unisys found 61% of Americans approve of the Internet kill-switch concept, this issue will require constant vigilance.
Tell your congressmen: Back away from the switch, slowly.
