Wow! I had no idea. Thanks for sharing. I'm not sure I would have hit this myself for two reasons:
1) I typically don't see a lot of mobile device adoption in my customer base 2) I typically don't see people stressing the limits of their CUCM device limits. I deal with a lot of BE6K size deployments, but with endpoints in the low hundreds.
