Actually I got tired about the “voice is dead” clamor and the “TDM is going to be switched off for good” crying that all those network equipment manufacturers keep preaching with almost religious fervor from their bandwidth-pulpits.
Voice is most certainly not dead. Our most recent big sales with major European carriers show this quite clear. They invest millions of Euros in voice technology from ECT. I have to admit however, that many of them are moving more and more towards all-IP systems.
We are currently migrating a large televoting system to an all-IP, virtualized version. It is one of the largest all-IP systems for this service in Europe and we are building it. And I realize when talking to customers, this is something that the market demands more and more, also on an international scale.
The advantages are pretty obvious. First of all it is much cheaper. You can virtualize parts of the system and run many modules on fewer servers and all that at highest availability. You decrease the amount of hardware which in turn means there is less maintenance and you still have the same capacity.
This is of course a big chance for smaller carriers and service providers who need to keep an eye on their costs even more than the big players.
I could go on forever talking about the pros and cons of the all-IP world. Yet all the cost-effectiveness happens at the expense of quality of service. It is simply in the nature of this all-IP world that you tend to have more dropped calls, lost calls, and disconnected calls than in the good old TDM world.
But the cost-advantage is obviously too tempting that is why I say, and it’s not hard to divinate, operators around the world will continue to ask us to migrate their value-added services to virtualized all-IP environments. I’m waiting for them to get in touch.
