Join Teams work meetings from Microsoft Teams (free) and vice versa

Microsoft Teams (Free) users can currently join Teams for work (or school) meetings only as guests, which requires them to use a browser and results in a sub-optimal experience. The new feature rolling out will allow these users to join Teams for work (or school) meetings in one click, without being redirected to the browser or asked to fill in their name/surname. They will also be able to continue collaborating with the meeting organizer and other participants via meeting chat after the meeting.  The feature will work in the opposite way as well, so Teams for work (or school) will just as easily be able to join meetings hosted by a Teams Free user with one click. This is associated with Roadmap ID: 167326

Note to self: Merging files before CUCM upgrade

I ran into an issue when upgrading (patching) a CUCM 7.1.2 tonight, and I couldn't see any readme files on explaining the problem. However, I came across a blog post mentioning something similar.

When you download patches from, they might be big and split into two or more files.
One way to merge them is using the "copy /B" in a dos prompt.

Example: When you have downloaded the two files "UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part1of2" and "UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part2of2", simply merge them by typing: "Copy /B UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part1of2+UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso_part2of2 UCSInstall_UCOS_X.X.X.XXXXX-XX.sgn.iso

The process will take a few minutes, and should complete with "one files copied" (You need to be in the folder where these files are located).

Once this is done, you put the merged file in a folder which you can connect to from the CUCM.
(Tip: I use xlite as a ftp server for this purpose :)
