Video conferencing is method by which people in different locations communicate in real time with two or more people at different locations via video This ability to see the remote participants as well being able to hear them has many benefits over audio-conferencing.

Video conferencing is now widely used by all industry sectors. Multinational companies use it to communicate with international branch offices, whilst smaller companies use videoconferencing to enable them to work with clients and suppliers in different countries.

The equipment required for video conferencing is simple to operate. On screen menus enable you to enter the number you want to call or select it from an address book. Gone are the days where videoconferencing required specialist technicians – now everyone in your office can be shown how to place calls with a 10 minute training session.

Video conferencing should not be considered in ‘black and white’ terms – there will always be a need to travel to meet clients or partners especially during the important early stages when relationships are being built. Where videoconferencing wins out is being able to maintain those relationships easily and cost effectively.

Modern video conference systems enable users to share documents and computer images with the remote (far end) party. When videoconferencing is used in this manner it becomes part of a collaboration solution.

Video conferencing is not only used internationally, many legal firms and consultants use videoconference systems to avoid billing clients travel time and to be able to carry out more client meetings in any given time period.

Many-to-many communication: this is the most complex form of video conferencing and is mostly associated with room based video conferencing technology. In this case several parties (more than 2) are involved in the conference, and all can be seen and heard.

Why use video conferencing?

A telephone call or e-mail is not always the best way to communicate with another person. Interactive meetings can help to generate ideas, and enable people to read and react to others’ sensitivities

Video conference communication and meetings are often much shorter in total as no travel is involved. A meeting that may take you away from work for four hours (due to travel) may take only one or two hours using a video conference. You can communicate more regularly with people in other districts or countries, which would usually be costly or impossible if you had to travel. Using video conferencing saves money as it can lower your expenses – there is no need for all the costs involved with travelling, such as meals and tickets

You can video conference with many more people than would fit into a single meeting room because each party will be using their own facilities, video conferencing allows for collaboration by document sharing. Many people in different areas can work on the same project and make contributions.

Many institutions can receive the same broadcast simultaneously and thus a much greater level of participation can be gained. For example, a lecture being broadcast to students at many different educational institutions

How do I use videoconferencing?

Videoconferencing can be extremely easy to use.  The most recent developments have been with 4 digit dialling opposed to entering in IP Addresses to connect to the far end.  This process would often be perceived by non technical users of the system as overly technical and would lead to a frustrating and clumsy user experience. 

We are all used to entering phone numbers in to mobile phones or fax machines where there is an on screen display of the number being dialled. Video conferencing is similar but with a TV as the onscreen display and a video image of the participants at the far end. Placing a call is easy, although there are advanced features available on most videoconferencing systems, these do not need to be used if not necessary.

What equipment do I need?

Video conferencing systems & equipment vary from entry-level systems where a videoconferencing unit (codec) is placed on top of a TV monitor, through to advanced ‘installed’ systems in boardrooms and meeting rooms. The latter require careful system design and expert installation.  CCOMM have been designing and building complex but easy to use main board room and meeting room installations since 1996.

Apart from the videoconferencing hardware a carrier is required for the communication between the near-end and far-end systems. This carrier can be ISDN digital telephone lines or IP based computer networks. Generally when organisations use video conferencing to speak to branch or international offices then IP (h.323) is used. When speaking to outside organisations it is most common to use ISDN (h.320).

DLL stands for Dynamic Link Library and is a file format created by Microsoft to get the concept of a shared library into full force in Microsoft Windows or the OS2 operating system. These files can also have the extensions OCX and DRV depending on the kind of files that they store. OCX is for files that contain ActiveX controls and DRV for system drivers. The DLL file format is composed in the exactly same way as the EXE file formats of Windows. The three major components of the DLL file format are code, data and resources which can be preset in any form and in any combination. What the DLL file format allows you to do is that it lets two programs using the same code run at the same time without the code being included in both the programs. This is what used to happen in earlier versions of Microsoft Windows. Here, the common or the shared code can be saved in a single file and can be accessed easily at the time of need when both the files using it get linked.

The great thing about a DLL file is that the code that is used by a number of files can be stored singly in a single unit of memory and does not need to be stored separately for each file that uses the DLL code. However, the exactly opposite thing happens in data sections. Each data section has its own private space. This is what makes the DLL file format extremely useful and handy. For linking files in the DLL format you have to import libraries. This can be done using C++ or Visual Basic or even Delphi and C. after the linking is done then you can use it to save space and perform more efficiently.

What is a virtual number? A virtual phone number – “virtual tel #” is a number without a directly associated telephone line. Such numbers are typically redirected to either a voice over IP (VoIP) device or service, or to another phone line, landline or cellular.

 

Virtual numbers are sometimes used together with mail drop service to create a “virtual office” in a separate location. A business may, for example, purchase a virtual phone number with NYC code 212, along with a mail drop (forwarding) service in Manhattan, to make an impression that the business is located in New York, when in fact it may be located in Utah or Nevada, or overseas – in a different country.

 

For instance, Toll-free phone numbers, or 800 numbers in North America, are virtual telephone numbers. For businesses or individuals located out of the area, or serving another city, a virtual local number in the other area will allow callers from that area to call without incurring long distance charges.

 

Virtual numbers are especially appealing to hi-tech companies (for international user support), exporters (to give the impression that the business is located onshore) and customer service outsourcing companies, such as call centers.

 

Can I get actual telephone numbers on my Skype™?

 

Yes. This service is offered by Skype™ and is called SkypeIN™.

It allows users to receive calls on their PC software when a regular phone subscriber dials their international virtual phone number.

 

Skype™ offers DID numbers in the following countries: Australia, Brazil, Chile, Colombia, Denmark, Dominican Republic, Estonia, Finland, France, Germany, Hong Kong, Hungary, Ireland, Italy, Japan, Mexico, New Zealand, Poland, Romania, South Korea, Sweden, Switzerland, the Netherlands, the United Kingdom, and the United States.

 

 Calls to the international virtual numbers are charged as calls to landlines in that country. Some jurisdictions, however, like France and Germany, restrict the registration of their telephone numbers to users with a physical presence or residency in the country.

 

I want a DID number (virtual number) in Bulgaria, Lithuania, Latvia, Russia, China, Iran or another country that Skype does not have. What do I do?

 

There is a way! Some virtual operators (ISTPs) will provide with a number in Moscow, St.Petersburg, Tehran, Sofia, Riga or Vilnius (to name the few) and they will actually send the call to your Skype™ software.

 

-       www.DIDlogic.com is an online DID exchange for those looking to buy DID numbers (virtual numbers) or sell their DIDs.

 

-       www.HotTelecom.biz also provides numbers around the world and can forward them to any number you specify, including Skype™

 

How do I buy virtual numbers for Skype?

 

In fact, you do not have to use Skype exclusively for the virtual number service. There are several alternatives to Skype™, and various SIP (Session Initiation Protocol) operators are sometimes a cheaper choice than Skype™. Let’s use www.didlogic.com as an example:

 

Your business is looking for a presence in China, however, you can’t get a Chinese number on Skype™. Log on to www.didlogic.com, purchase a number in China, and set your destination to you Skype™ username. The number will arrive to your Skype™.

 

You really want a virtual number in Moscow, Russia to talk to some girl you met at the Russian embassy reception, but have no idea where to get it. Log on to www.didlogic.com, purchase a number in Russia, and send it to username@sip01.sipphone.com Use free Gizmo software. You don’t even need Skype™. Forwarding is free.

 

You are an international security contractor with some really good prospects in Riga, Latvia. You must get calls on your US number, and you need it setup fast. And Skype™… well.. does not offer this. Not a problem! Log on to www.didlogic.com, purchase a number in Riga, Latvia, and send it to your Google Talk™ software by entering someuser@gmail.com (yes, you may also use Google Apps and send it to your hosted Gmail service). Answer calls on Gtalk – forwarding is free.

 

Finally (for the really technical types) you can use didlogic.com to send calls to any SIP capable device, including Asterisk. If your service provider allows you to receive SIP calls from outside the network, you can receive calls on just about anything – any betamax clone like voipcheap.com (user@sip.voipcheap.com), or FWD, anybody in Sipbroker.com peering list – you name it.
