Are you using the sample app included in the SDK package?

Note, that two components must be installed on the PC:

     - The browser-specific extension (i.e. the Chrome extension it sounds like you already have installed)

     - The OS-specific Jabber add-on (available here: Cisco DevNet: SDK Web SDK - Voice and Video - Downloads and Docs
