Computer Telephony Integration- CTI

No Comments

Computer Telephony Integration is a technology that permits integration or co-ordination of interactions on a computer and a telephone. It is also known as CTI or Computer-Telephone Integration.With expansion in the contact channels from voice to advanced methods like web, fax, and email, the description of CTI has also been expanded to incorporate the integration of all the above mentioned methods with computers.

Overview

A person using a CTI enabled computer will be able to dial a number, answer a call or end a call from his computer itself. It also provides the facility to dial a number from an address book saved on the computer. Many CTI systems also allow users to co-ordinate with teleconferencing systems. CTI is generally sorted into two categories:

  • CTI allows user to control the telephone system.
  • CTI allows telephone system to show the data through the computer.

Functions of CTI

Using CTI, the below mentioned functions can be implemented:

  • Call information display to authenticate the telephone number of the caller
  • Identifies a voice for message forwarding or authentication
  • Determination of the procedure to process a call by using recorded voice or an already entered input
  • Offer IVR (Interactive Voice Response) for callers
  • Match the caller’s number with customer data and show it on display for the sake of reference
  • Handle video and voice conferences
  • Route the fax messages to the correct fax machine
  • Pre-dial callers for outbound calling
  • Agent state control- for instance, after-call work for a particular duration, it automatically switches over to the ready state

CTI Event Flow

A normal CTI application handles the event flow that is created by the telephony control during the entire process of a call. The sequence of events is as follows- call setup (initiating), call delivery (ringing), call establishment (answering), Clearing a call (hanging up) and ending a call. The other events that can be managed by a CTI during a call are- conference call, call transfer, call forward, hold a call and retrieve from hold.

CTI also has the ability to manage events associated with Automated Call Distribution (ACD) like- agent available, agent not available, agent ready, agent not ready, agent logged in.

Standards for Computer Telephony Integration

The standards for CTI application are:

  • TAPI (Telephony Applications Program Interface): This is the Microsoft standard for CTI.
  • CSTA (Computer-Supported Telephony Application): This is a European Computer Manufacturers Association standard for CTI and is approved by ITU.
  • TSAPI (Telephony Service Application Program Interface): This is a standard by Lucent/Novell/AT&T for CTI.

The Bottom Line

Computer Telephony Integration is thus a robust collection of library routines that allows the application programs on your computer to co-ordinate with the telephone system. This is achieved by merging the ability of your telephone system with the functionality of your operating system.

The Difference Between a VGA and SVGA Cable

No Comments

In a desktop computer setup, the VGA cable connects to the system unit to display on the monitor, The VGA cable transmits analog signals and can support resolutions up to 640 x 480. While the super video graphic array (SVGA) can carry analog signals and support resolutions up to 800 x 600. SVGA is the enhanced VGA, and it is also called Ultra VGA. Almost all SVGA cables today will support far higher resolutions other than the usual 800 x 600 standard resolutions.

Features.

These cables have plugs with their pins arranged in three rows: The first row has 5 pins, and the last rows has 5 pins too, but the middle row has 4 pins, it does look like a pin is missing, but on a contrary no pin is, in fact, missing that’s the 14-pin standard configuration. These cables will plug into any high density, VGA ports or sockets, or on any computer monitors and other compatible devices and display adapters. It’s hard to differentiate between an unlabeled VGA and an SVA cable by mere looking at it, if you have an SVGA cable connected to any compatible device or any graphics card, a default resolution of 800 x 600 should become available.

Size

Cables that are unlabeled in most cases are SVGA cables other than the thinner cables. This is because these SVGA cables normally have much shielding than its other VGA counterpart.  If the cable is very thick, then the quality should be great.

Significance

 SVGA cables will require more video memory and graphic than VGA cables, SVGA cables supports up to 16 million colors. But with VGA cables you will only get a maximum 640 x 480 resolution, in only 16 supported colors.

Cable Quality

For better and high-resolution signals to be carried for long distance one will be required to use a better cable than that of the lower resolution signal cables which transmit over short distances. You might face problem of poor signals such as no images or blurred images as a result of using poor quality cables.

Warnings

When shopping for a new cable, not just VGA cables now, always check first for the configurations of its ports to be used. Female configurations have the hole parts, while the male has the pins, check if the number of rows and the number of pins corresponds. VGA cables from primecables.ca are very thick and will offer great visuals. Please note that old VGA and SVGA monitors will most likely not work with newer HDMI or DVI cables.

How VR Has Changed the Entire Experience of Mobile Games

No Comments

Nowadays, all of us are hearing the word called Virtual Reality. As per media reports, it might be a game changing experience for the entire digital medium. To grab the opportunity, now there are several companies launching virtual reality products ranging from headgear to VR-enabled games. In this space, Google Cardboard and Oculus Rift headsets are standing at the pole position. Earlier, when these devices were in the market, there were several issues with compatibility, resolution etc. But as time passed by, the display resolution and other stuffs are also increasingly improving. Now, the headsets are supporting 1080 X 1200 display resolution too. And not only that, now one can enjoy high frame rate per second (90 frames per second) using the headset, which helps them explore much more details on the screen.

With this huge improvement, the gaming experience has also changed and now gaming companies are trying to incorporate VR technology into the games as gamers will get a much more realistic feel rather than just viewing it on the screen.

In this phase, both AMD and Nvidia had made clever software tricks, which were designed to let the user experience gaming in much more realistic way. Especially they had incorporated more frames from GPU; AMD called its VR software LiquidVR and Nvidia’s is called VR Works.
As we already discussed, the power of more frame means more graphics and heavy games can be played on this VR-enabled headset.

AMD’s LiquidVR is backed by two or four GPU, which enables the enhancement of performance along with the same Nividia’s VR SLI. It’s already present in the domain, which is backed by SteamVR Performance Test.

So, to grab the attention and get more market share, game developing companies are trying to adopt the new technology. In this league, several games are ready to launch with VR technology.
Lucky’s Tale is one example, which supports Oculus Rift. In this game, there is a character called Mario, which is available in 64 different styles and looks fabulous on the in the 3D platforms. It is one of the fabulous games in the VR games segment. As we know, this game is known for its visuals and so in 3D too all the stuffs are easily replicated.
