One potential issue preventing OCS and Lync adoption could be the relative lack of features that have been built into existing PBX systems over a number of years. One such feature is the ability to immediately record a call to a client account. This is a very common requirement in the Legal industry where Lawyers must be able to quickly and easily record their phone conservations with clients and bill for that time.
Microsoft are relying on the development community to fill the gaps of niche applications. Enabling Tech Corp are one such company and they have developed a time tracking integration for OCS R2 and Lync.
Take a look at the video below, the demo of the application begins at the 3.00 minute mark. I’d be interested to know how many organisations could exploit this app, I know several large Law firms are heavy users of OCS.
