We have a Lync 2010 server set up along side a Polycom HDX7000 which acts as a Lync endpoint. This works well for Windows Lync users who can dial and have video conferences with the device.
When a Mac client attempts to connect a connection is made, encryption is enabled and audio works fine, however attempts at video yield "Video call invitation was not accepted." on the client with little other errors.
Mac to Windows works fine. There are no firewalls in play (all on the same LAN).
Anyone have any ideas on where to start looking?
