The first time I encountered voice over IP it was 1999. I started working for a startup trying to develop a gateway product that would ease the transition between legacy telephony and the next generation of voice over IP services.
I remember we used to brainstorm the issues ahead. The eternal comparison with legacy services: Quality of service, other line services as call transfer, call forward and the rest, the need for VoIP to interoperate with legacy private branch exchanges that most companies would maintain for at least 10 or 15 years. Hence we developed all flavours of ISDN and even analog gateways. Then it was supposed to be part of a system, so it should be based on open standards like SIP or H.323.
The product ought to be reliable, scalable and needed to implement some kind of redundancy. And conferencing. We needed a conferencing solution.
Then the problems with emergency numbers and different national telecommunication regulations.
And finally, encryption. Nobody would want to broadcast their conversations for anyone to listen.
By the time I left the company we had only achieved part of this. By then the industry had matured and settled and it was already 2005. We offered better services than traditional telephony, better prices, similar quality and encryption.
And during all that time I had that feeling inside me that all of these was too complicated. I don’t like transitions, they are a waste of time. By the time you have finished with the details everything has moved on.
And that is exactly what happened with VoIP.
In the meantime, the Internet had exploded. The increase of ADSL usage was meant to push the VoIP market, but what really flourished were point to point networks. People using file sharing programs. People using instant messaging. The technology interested me immensely, there were huge possibilities.
Developers were working on peer to peer cached searches, even the distribution of audio over p2p networks.
My colleagues didn’t believe on it. We had a business model and the market was growing.
And then Skype erupted into scene. A peer to peer VoIP application. A well thought business model based on mature technology. And as always happens, everything was clear then.
Forget interoperability and standards. Forget competing with legacy telephony. Forget quality of service, let the network deal with it. Forget bandwidth requirements, the network will also deal with that. Don’t bother with regulations as emergency numbers. Don’t aim to substitute existing services. Just offer what you have and let the people decide how to best use it. And don’t rely on central servers, go with the flow and built up peer to peer networks.
I have to admit I don’t use it personally, but it didn’t feel completely right to see their success when they didn’t solve any of the problems. That’s the market way.
VoIP as I saw it was a clash between two worlds. The Internet as represented by IETF and SIP, and the telecommunications arena, with the ITU-T and H.323. In that war it seemed that the Internet would win. But then, the magic of the Internet is its flexibility. It doesn’t have to wait for regulations and standards for things to work. They can always be standardise later. So Skype came along with all that p2p experience and in just a couple of developing years had a product to swamp the market.
And still “serious” companies don’t like peer to peer. Investors and share holders don’t like the word. It’s controversial (Isn’t that like stealing?). Too many noise by the likes of the RIAA. In the same way as Open Source is not welcomed everywhere (what, you’re giving away my/your work for free?).
It is sometimes difficult to separate the technology from its uses. Both peer to peer and open source technologies have wonderful advantages, and in my opinion they have the future in their hands.
The Internet has revolutionised the telecommunications world. Skype is just an example. I think ultimately people will just plug a VoIP phone to their telephone line and forget about Skype, but the companies offering the service are still too tightly regulated. Skype’s advantage is their direct relation with the users.
Now, it’s time for the Internet to revolutionise the broadcasting industry.
Last year I changed jobs. Guess what, I joined a startup and we are developing an IPTV product.
