I am evaluating the possibilities of integrating Lync with Salesforce. Ideally the requirement is to engage the customer over a video chat. The Agent from the Service Console will click on a Button, say "Go to Meeting" which should automatically create a meeting request and mail the contact with the meeting URL.
We did evaluate an App 'Blue Jeans' but it required chatter to be enabled and cannot be launched via a button.
Any pointers (either an app or via customization) using Lync to engage the customers over a Video chat will be much helpful.
You should check Weemo . You can Add a video chat button to any web page or mobile app and connect customers to a live video customer support call or escalate a chat session to video.
