We currently use Sony Video conference units for our end units. On the backend, we use a Cisco 3515 for multipoint conferences.
We now need to be able to do video conferences with external parties using our MCU.
Since there are many ways of doing this, are there solutions that work better than others? Basically I need to publish a doc that says 'here is what you will need. This port open on your firewall, a public IP address that is not NATd....'
Any help would be appreciated.
