Yah, you're right. Good point of view.But in my country we usually don't use video at all. And we usually have problems with the carriers because that. So the faster solution is to remove it directaly from devices.But the best manner to workaround it...

I think is easier to remove the video options directly from the phone config in CUCM.The video capability is enabled by default to Jabber phones.Phone Configuration -> Product Specific Configuration Layout -> Video Calling = Disabled.
