1. There is no license needed for CUV Desktop client, it can be installed on as many PCs/Mac as you wish to install on
We do license connection to MCU and so you have to ensure you have enough MCU ports and CUV-Manager licenses
to access these ports. There is also license for CUV-Desktop server, which comes in bundle for CUV-Manager license
with no additional cost
2. CUV-Desktop client does not register, it is only used during the live participation in the conference, just like active
X plug-in for WebEx. It will only be used when in conference, else it will just be sitting as software on your PC.
Cisco does not offer P2P call with Desktop Client, this feature was removed from our roadmap. If you need
P2P functionality you have to deploy the CUCM with our software clients (CUPC, CIPC, CSF etc)
3. You need to ensure you have enough ports. Each client will consume one port "connection" on the MCU
when participating in the conference. In addition to this, there will always be one extra port used by the
desktop server for each active conference in progress. If you enable recording during the conference, that
will consume another port on the MCU for the duration of the recording.
