Microsoft Lync: The Pros and Cons for Enterprises

While it is clearly a good UC choice for customers with needs that align with Lync's strengths, it's not yet a platform that can jump in readily to replace traditional PBXs in environments heavily reliant on traditional desktop phones, experts say.

Still, Lync is getting closer and its new features are bringing it into closer parity with UC leaders such as Cisco and Avaya, they say.

In touting upgrades to Lync 2013 - no release date has been set - Microsoft highlights its adoption of H.264 scalable video coding (SVC), a video codec standard that makes it relatively simple to display video on a range of devices, meaning Lync can support participants on screens ranging from smartphones to room displays, says BJ Haberkorn, director of product marketing, Microsoft Lync.

In addition, video displays by Lync clients has been upgraded to show up to five participants on screen at the same time, an improvement from having just the active talker on displayed. The view of those five is optimized depending on the number of participants and what other conference tools are being used.

Lync 2013 adds voice and video over IP for all devices, meaning that a device connected to a Wi-Fi network can participate in audio and video calls despite being disconnected from a traditional phone link. So users equipped with smartphones and tablets can conference over IP networks.

This is especially important to iPad users, he says, because the devices don't support cellular phone networks. So they can join conferences, register presence and instant message other Lync participants.

The latest Lync client supports Windows 8 with a reworked interface that embraces touchscreens, which he refers to as the Windows 8 paradigm.

Peer-to-peer voice and video service Skype is federated with the upcoming Lync server. That means a corporate user working off a Lync enterprise network could provide and receive presence information with users of Skype. They could also establish audio calls with Skype users, but not video calls. Microsoft has that ranked as the next feature it will work on after the initial release of Lync 2013, Haberkorn says.
