Office Communications Server (OCS) with Exchange and Unified Messaging is already becoming disruptive. Our offering makes it easy to pay for the initial deployment of OCS out of an existing conferencing budget. Once the customer sees how easy it is for us to slip this into their operations, we'll show them how to start expanding their use of OCS, adding presence, video, etc., and then move towards dumping their expensive PBXs.

Microsoft is being very clear that they intend to see Exchange users be able to power down their PBX and legacy voice mail systems. I haven't had a PBX phone for six months, and we're very close to just turning off the PBX and having only SIP trunks.

So I agree, that's where the disruption happens. I just think that in the process, conferencing bills are going to get a lot smaller. Mine sure did.

Bottom line VoIP never really delivered on the promise of zero cost transport for business use – the telcos just lowered their rates to make VoIP just another way to connect a call.

The big change is the cost of the hardware to do a conference call and still waiting in the wings is international. In my mind – the big revolution on conferencing will be one price per minute globally (around 5 cents a minute or less – business grade).

Now what you can do in the call and how it all links to tools you already use like Exchange will potentially be disruptive.

So are we at another disruptive point in conferencing – I don't think so based on price. Disruptive service offerings must be price competitive but offer a ton more functionality and integration – and hopefully a true international solution. Price is just no longer the issue. Just my .7 cents – and I need to forget this stuff as well.
