I have read the online document from lifesize that have how to config the Lync (http://www.lifesize.com/cloud-help/en/configure-lifesize-cloud-microsoft-lync-2013-federation.html) but it not clear to me. Have any more detail document ? and does the cloud need to config for Lync or not ?
As I know, the Lync client can dial to cloud by 'email@example.com, is it right ? But how to dial out to Lync client from cloud ?
