What is IP based video conferencing and How can I do it from home

Question

A company wants to interview my neighbour. They say they will do it via IP based video conferencing (and said she must go to a reliance webworld center - which apparently has that facility in our country India).

What exactly is IP based conferencing? Is it possible to do it from home? (We have webcam) What software is required? (both Windows/Linux suggestions will do).

Answer 1

IP videoconferencing in the business world typically consists of dedicated videoconferencing equipment which operates purely over the internet (as opposed to early technology videoconferencing which operated over public or dedicated phone lines). It is entirely possible to do it from home if you have a broadband internet connection, a dedicated external IP address (required in many cases) and equipment that is compatible with the person you are trying to connect with. While there are some common standards out there and the problem is nowhere near as bad as it once was, there are some lingering issues with compatibility between equipment.

Most webcams, however, aren't going to work because they lack the necessary software to make the connection and will not provide the level of stability and quality needed. The dedicated equipment and/or software is typically quite expensive. The company likely gave directly to go to the center because they knew it was already set up and would work. A company is not going to be patient with an interviewee if you spend the first 10 or 15 minutes trying to establish the connection.

Yes, you can definitely have an IP based video conferencing session directly from the comfort of your home. All you need to have is a reliable internet connection. The rest of the things are secondary.

You should be having a static IP address connection in case if you want to receive a call. Think of it as a mobile number. You give your phone number to people and they call you dialing your number. Same is a Static IP address that doesn't change. Most of the ISP can give you instantly. After that, there are ports like 1719 and 1720 should be opened on your iP address as well. One is signalling port and the other other is traffic port.

Now, you are all set to have an IP based video conferencing from your home. You can donwload Polycom M100 Video conferencing Software. Download that software and select H.323 in preferences if you want to dial an IP address of the far site. Bingo, You will be instantly connected.

Answer 3

It depends largely on the equipment, software, and its component standards whether or not it can be done at home. If they are using industry standard SIP, a soft phone client that supports video conferencing should be all that is needed. If they're using something like Skype, or another proprietary system, then a compatible system will need to be used. Sadly Video over IP is still a bit "wild west" when it comes to standards, and not everyone conforms to SIP yet.

Answer 4

Yes you could do it from home, if you buy the supported kit with camera and microphone. There are a couple of Cisco products, but they are quite expensive and I think there is one Linksys one. If she needs to go somewhere to do it, that means they already have a video conferencing terminal setup with cameras and screen and everything.
