No that´s not possible, because skype uses a proprietary protocol.
You can have a look @ the solution from Blue Jeans Network. By using this service you can connect skype and polycom endpoints.
Thanks for the response. Do you know if the HDX 7000 can work with other tools like Google Talk or something similar? Or, is it in the same boat as Skype?
yes it is in the same boat. Its not H323 (standards based video over IP)
the blujeans service does enable google talk though. and Skype and lync etc
There are several ways to connect Skype with the Polycom HDX systems.
Our VSS-1 system is a stand-alone hardware/software add-on for your existing conference room videoconferencing system (SD & HD H.323 or SIP standards based )
It works with most of the current Polycom HDX systems, as well as the legacy Polycom VSX and ViewStation systems.
The features and benefits of this system include - support for Point to Point calls, Multi-Site Room to Room calls (via H.323 or SIP), and Skype Multi-Site Group Video Conferencing, plus streaming & recording. It provides full Skype capabilities - video, audio, chat, file transfer, SMS, screen sharing, etc. More details of the VSS-1 system are at this link - http://www.1pcn.com/skype/polycom/index.htm
