@arienne - I am good thanks, hope you are too! The ad hoc conferencing functionality in the client was never meant to be removed. Actually it wasn't, a bug was causing it not to show up correctly. This was fixed some time ago. However we have now taken the opportunity to improve it even further, there will be an update early next week. Ad hoc conferencing should definitely be in the clients - thats a promise

In regards to feature changes - I will make a separate blog post about this in the coming weeks to explain better because i think there is misunderstanding around this.
@mchristsen - thank you for your feedback. Yes you can easily add users to an existing conference by phone number. Old functionality is back but we are improving it, check out our blog next week.
In regards to Outlook - the old method of adding by email and not using a calendar app will be back in SP3. Integrating with the old outlook desktop app is difficult, our focus is on Office 365. Thats where Microsoft has its APIs anyway. Being able to select extensions from the web client and quickly setup an audio conference makes sense, we will be doing it. Re your and Randalls request we will discuss it internally.
@oksio - Making a softphone integrated in our webclient using WebRTC is in our to do list. To make a really good one is not a trivial task though, so it will take a bit of time. Meanwhile a softphone and a web client are two different things - a user should be able to understand that in my view. Scheduling a conference from our clients - we will discuss.
@Randall - Yes we have decided to add it back, we will be researching how and when it can be done.
In addition we are going to add a schedule conference option in the native clients.
