Voice resiliency is by far my favorite feature I like to demo with Lync 2010. How many times have you been at a hotel with a lousy wireless connection and the moment the connection drops so does your call, then only to have to dial back in. Well that has changed with Lync. So the screen shots I have taken aren’t all from the same call. It was a bit hard to get a complete sequence in one go so I had to do it over a few times to get the screen shots but this is a good flow of shots of what it actually looks like.
This first screen shot I have a call up to myself. This happens to be my cell phone and as you can see it is resolving it to me because of my published cell phone number.
In this case I have disabled my wireless connection and I have hardwired Ethernet plugged into my laptop so that I can easily simulate dropping a wireless connection. Next shot I have now disconnected my Ethernet cable.
Not only do I have an indication that the server connectivity is limited but the call bars are red on the call window and the client has logged me out.
Next I have plugged the cable back in and you can see the call has been reestablished and the audio is flowing again but the client is still logged out.
Lastly, the call is back up and the client has reestablished connectivity. This is a cool feature not just for demo but has real practical use when you network connectivity is being affected and your call is dropping in and out. A few weeks ago I was in the situation I described and had network connectivity issues. Rather than just give up because I had to keep reconnecting, having the ability to automatically reconnect took some of the pain out of the situation. Beyond that it shows the thought that has been put into the user experience with Lync. You are full informed of what is happening the whole time. Had this only affected the client the audio would never had dropped which is an important part of keeping voice up and active during adverse network conditions.
Next post we will take a closer look at what is going on under the covers.
