Very interesting article. I try to describe the situation as I have understood.(1) Technology
We know long time already that:
1. PC CPU-s and networks become faster and faster making it possible to have normal quality desktop videoconferencing.
2. Laptops are more widely used meaning people want to work mobile.
3. Firewalls and private IP-addresses are the main hindrance for VoIP.
(2) What people want
1. Users would like to have unified conferencing: to be able to mail, chat (IM), talk and see each other.
2. The UI has to be convenient and fast.
(3) What people have
1. ViaVideo. It's portable and normal quality, but:
- little-bit too big to carry around
- you can call only to limited number of users (firewalls, etc).
- user interface startup not very fast
2. Web conference. It has familiar UI and doesn't require any special software to be installed. Nevertheless:
- it does not often offer (firewall friendly) support for voice and video over IP
- you have to set up a web conference, you are not "always connected".
3. Messengers, a la Windows messenger. Messengers are good because they have convenient global directories; they require almost no user invention after first configuration. However:
- to use data or voice conferencing you have firewall problems.
4. Skype - VoIP and IM software that goes through firewalls. As convenient as Messenger, but now (in beta state):
- is point to point only
- offers no video nor data connection.
(4) What may happen next
1. I may be too conservative but I think business customers are going to use POTS PBXs for long time:
- price per user is cheaper that with VoIP
- it's very reliable while it is very mission critical
- it is everywhere
The main reason to have VoIP on desktop is mobility. However, most people have mobile phones to achieve that.
In conclusion I doubt PBX manufacturers are going to be strong players in unified messaging / conferencing field.
2. Microsoft's idea to have video as a feature of the messenger is very good. Microsoft offers a global directory service and does it free of charge. Their aim is to sell Windows as a desktop OS and they are ready to offer many services free of charge to make Windows competitive.
However, messenger video is p-to-p and firewalls are still in play. It's no problem if you want to communicate within a company only. But globally the problems can be overcome by help of CSP-s.
3. Idea of integrating firewall-friendly web confernce with messengers (like Click to Meet) seems to be good idea as well. In case the UI is really comfortable.
(5) In conclusion.
Maybe I'm too myopic to see strong disrupting PBX - conference convergence in near future.
There will be a need for multipoint voice / video (/ data) conference service, so there there will be room for CSP-s in the market.
The need for high quality group conferencing solution remains. As the number of sold group systems is not very big (around 700k?) this market shouldn't change very much.
IPv6 should cease firewall problem in some years. It will boost unified messaging.
I'm I wrong somewhere?
Marko, waiting for your feedback
