A conference call is a telephone call in which the calling party wishes to have more than one called party listen in to the audio portion of the call. The conference calls may be designed to allow the called party to participate during the call, or the call may be set up so that the called party merely listens into the call and cannot speak. It is often referred to as an ATC (Audio Tele-Conference).
Conference calls can be designed so that the calling party calls the other participants and adds them to the call. In most cases, the participants are able call into the conference call themselves, by dialing into a special telephone number that connects to a \"conference bridge\" (a specialized type of equipment that links telephone lines).
Usually, most companies use a specialized service provider who maintains the conference bridge, or who provides the phone numbers and PIN codes that participants dial to access the meeting or conference call.
Three-way calling is available (usually at an extra charge) for most customers on their home or office phone line. To three way call, the first person one wishes to talk to is dialed. Then the Hook flash button is pressed and the other person\'s phone number is dialed. While it is ringing, flash is pressed again. This will put the three people together. This option allows callers to add a second outgoing call to an already connected call.

Server farms go solar - Oct. 4, 2007
Server farm goes solar
A data storage company generates all its own power using solar panels.

(Business 2.0 Magazine) -- Massive data centers are vital to the economy. They are also notorious power hogs. If their numbers keep growing at the expected rate, the United States alone will need nearly a dozen new power plants by 2011 just to keep the data flowing, according to the Environmental Protection Agency.
That\'s why a small server-farm company called AISO.net (for \"affordable Internet services online\") has gone completely off the grid. Located 80 miles southeast of Los Angeles in the desert hamlet of Romoland, AISO.net has flanked its 2,000-square-foot building with two banks of ground-mounted solar panels, which generate 12 kilowatts of electricity. Batteries store the juice for nighttime operation.
To slash energy consumption, AISO.net switched from 120 individual servers to four IBM blades running virtualization software that lets one computer do the work of multiple machines. The cooling system cranks up for only about 10 minutes an hour, and when the outside temperature drops to 60 degrees, air is sucked into the building to cool the servers. Solar tubes built into the roof illuminate the facility's interior.
The service is attracting plenty of eco-conscious clients. Al Gore's Live Earth concerts were webcast on AISO.net's servers in July. And San Diego startup GreenestHost is reselling AISO.net's services to mom-and-pop website operators who want to go carbon-neutral. "Small data centers could easily start to adapt and make changes like this," says AISO.net co-founder Phil Nail, who claims the project cost about $100,000.
His monthly electric bills, once as high as $3,000, have dropped to zero. Larger data centers can't match that. But Sun Microsystems (Charts, Fortune 500) did recently slash power consumption 61 percent by consolidating its Silicon Valley servers into a single state-of-the-art facility. And IBM (Charts, Fortune 500) BladeCenter VP Alex Yost sees growing demand for energy-efficient servers like the ones AISO.net uses. "It's an enormous economic opportunity," he says.
