Lync Multiple Points of Presense (MPOP)

With the exception of Microsoft Lync Attendant, Lync Server clients support multiple points of presence (MPOP). A single user can be signed in at multiple locations. Lync Server presence has the added flexibility of being read from multiple endpoints simultaneously. This enables a user to be signed in at multiple locations or endpoints that publish presence independently. The server then aggregates these endpoints and forms a single presence class that is published to subscribers. Lync Server determines which endpoint is currently most active for that user. For example, a user might be Away at two of the three endpoints, so the server sends the message only to the endpoint where the user is Available. If the server is unable to determine which state is most active, it sends the message to the endpoint it determines most likely active and waits to see if the user acknowledges the toast at any location. If the user opens the toast at an endpoint, the server removes the message from the other endpoints. If an endpoint doesn’t acknowledge the message, the server leaves the message at only one location which is the most likely endpoint. You cannot control how long the client stays logged in for, but you can control how many Lync clients a user can log into at any one time. You can do this by using the -MaxEndpointsPerUser switch in the Set-CsRegistrarConfiguration cmdlet. The default is 8 but you can set it from 1 endpoint to 64 endpoints using this cmdlet.

Reverse Proxy Solution for Lync Server 2013


Looking for a reverse proxy replacement now that Forefront Threat Management Gateway (TMG) 2010 has been discontinued? Well, it is now possible to add an optional component called IIS Application Request Routing (ARR) 2.5 to the Internet Information Services (IIS) role. This component enables IIS to handle reverse proxy requests, URL rewrites, and load balancing.  IIS ARR is supported on Server 2008, 2008 R2, and 2012. And it’s also supported On Windows 8, 7, and Vista with the Web services features installed. So why is a reverse proxy required?  Lync Server uses two websites to service its web requests, one for the internal network and one for the external network. The external website listens on port 4443, instead of on the standard port 443. In order to do port translation a reverse proxy is required to translate between the two websites.

Lync Online Office 365 How to Add or Modify Dial In Conferencing Numbers

Dialin Conferencing numbers are assigned via the “Lync Online Control Panel”. For a single user go to the  Microsoft Online Portal, navigate to the Lync Online management tool, and then go to User management. To assign a single user, select the user and open their Lync properties. At the bottom of the configuration screen, you can select an audio conference provider and type in phone numbers and passcodes for the provider (note: it is important to enter only the numbers as the screen shot shows and avoid any dashes, dots, or parenthesis). Save the user profile. If adding bulk users or need additional information on the above procedure refer to: http://community.office365.com/en-us/wikis/lync/1715.aspx

Lync 2010 AV Conferencing Pools

Regarding Lync AV Conferencing pool, all Front End pools of a Central Site use the same A/V Conferencing server or pool. Each site can have only one A/V Conferencing pool. This pool can support multiple Front End pools at that site. There is no limit on the number of servers in an A/V Conferencing pool.
