Lync Server 2010 Voice Planning Webcast Q/A

For those that missed the Lync 2010 Webcast on Voice Planning, I’m submitting the Q\A from the session.
Questions and Answers Log:

Subject: TechNet Webcast: Microsoft Lync 2010 Voice Deployment (Level 300

Question: Does Lync 2010 offer a small business solution for companies as small as 5 users? What would be the initial cost and the cost per user per month for a small business for all the equipment, and services including unlimited nationwide long distance?

Answer: No, Lync 2010 is not offered in small business solution.

Question: Our business wants to know how many voicemails are in a user’s mailbox (not-listened-to and listened-to). Do you have any reports like this?

Answer: Exchange 2010 Unified Messaging has reporting tool that allows you to gather data as Call Statistics and User Call logs, you can find more information about the tool here

Question: You would also want to not colocate if the SIP gateway you use can only listen on 5061,,,collocating changes the port to 5068

Answer:  Having a SIP Gateway that can only listen on 5061 could be a possible reason not to collocate, however the more common reasons for deciding on collocating the mediation server on the front end pool are if you are using Media bypass or not; because not leveraging media bypass means the mediation server is transcoding traffic which uses CPU resources.  In addition rather I’m doing direct SIP or SIP trunking or not will have an effect if I collocate the mediation server or not. 

Question: What tpe of Equipment works with Lync? I keep hearing about Audiocodes and Dialogic. are these the only ones.

Answer:  You can find a listing of supported equipment at the site referenced here


Lync Server 2010 Deep Dive Conferncing Webcast Q:A

I delivered a webcast last week on Lync 2010 covering Conferencing.  Below is a transcript of the Q:A.

Questions and Answers Log:

TechNet Webcast: Deep Dive: Lync Server 2010 Conferencing

Question: Why did you not use Lync Conferencing for today’s conference to demonstrate how easy it is to use?

Answer: We will eventually switch over, but to minimize impact on customers, we chose to continue to use the existing Live Meeting infrastructure that was put into place for these types of large scale webcasts.

Question: I have switched to Windows 7 Phones can i attend a Lync conference on my Windows Phone 7 I have not been able to do Live Meeting with Windows Phone 7?

Answer: The Lync Client for WP7 is not currently available so it is hard to speculate as to whether this feature will be supported at relase. I’m sure it is being considered, but am only speculating at this point.

Question: I apologize but I am unable to use print to PDF on slides – will it be comfortable to share the slide in pdf format via handouts?

Answer: I will post the slide decks sometime next week so keep an eye out on my blog –

Question: Are all the Lync conferencing features being discussed available in Lync Conferencing available on Office 365 or are some features only available with on premise Lync?

Answer: Not all features in Lync Conferencing when deployed on-premise is available in Office 365. I don’t have the list of what those are though.

Question: Can you comment a little more concerning the SQL cluster restrictions?

Answer: I am not able to hear what Bryon is saying, but the specific TechNet article for configuring SQL for Lync 2010 is here: The key is to make sure the SQL cluster is configured before you install the Lync Front End component.

Question: If the guest client invited to the meeting has Lync but they are not part of my domain do the external guests still use their foreign lync client or do they join with the web app?

Answer: Either one can be used.

Question: does the “show the link to user to join meeting using Legacy client” security option, allow a attendee use the live meeting client to join a Lync conference?

Answer: No, it does not. That is for Communicator clients.

Question: Are Lync Conferences integrated into Outlookso i can schedule or meet now directly from outlook? Does it use the old Live Meeting Outlook add-in or is it a different addin?

Answer: there is a Lync Add-in that gets installed when you install the Lync client.

Question: if you have a seperate A/V pool, does the web conf components still get hosted on the Front End servers.

Answer: yes.

Question: Any advantage or points to consider for enabling/not enabling show legacy client or show attendee link?

Answer: If you are hosting meetings that include external attendees who may not have Lync, I think it is a good idea to at least point the user to download the Lync Attendee Client. I don’t know about “official” advantages or points for consideration. I will check with Byron for his thoughts and post on my blog later.

Question: If a Lync server homed user creates a meeting with Livemeeting client and sends the invite to external users. Will the users join the meeting through the R2 Edge server (assuming it is still avaialbe)

Answer: If a user is hosted on a Lync server, they will not be creating meetings with the Live Meeting conference so I’m not understanding your question here.

Question: Where is the alias defined in the short url? Does it pull from AD? Is this adjustable? can you turn off the simple url?


Question: during migration, we will have users on a Lync server but still running Communicator and Live meeting. during that stage, before we depoy the lync client, will the external access still work via the R2 edge for the users that have been moved to Lync, but not yet running the Lync client.

Answer: You can connect using Communicator, but Live Meeting will not connect to a meeting hosted on Lync.

How to find out how many Lync users are enabled?

I just recently was asked this question which made me do some digging.  Now you may be aware that in previous version of Lync leveraged the GUI for a lot of the retrieval of information.  One of the items you were able to find out was how many users were enabled for OCS. 

Well with Lync server that information isnt readily available as easy.  Now through cmdlets we have to retrieve that information.  The example below shows the cmdlet that is applied to retrieve that information.

Hope you enjoy and are now enable to see how many users have been enabled for Lync.
