As Olek already mentioned probaly it will be better if you can upgrade the exiting MCU.

Currently you have 12 video / 12 audio ports on 4205.

You can consider for example upgrading to a 4215 ( 30 + 30 ) or even better to a 4220 ( 40+40 ports)

Upgrading the exiting MCU 4205 is a good idea, it 's better solution.

How to upgrade to a MCU 4215 (30 +30) from MCU 4205 (12+12)?

Now, I don't find any upgrading license for MCU 4200 Series yet.

Please give me more directions!

Thank you very much

This is not an upgrade. You buy a new MCU and old MCU to return cisco. There is a proposal from cisco - trade in for MCU.

You need to contact your local cisco representative for details.
