As Mobile World Congress winds down in Barcelona, we've wrapped up more than 200 customer meetings and rubbed shoulders with a wide array of partners, industry analysts and news media. Mike Z met personally with customers across Europe, the Middle East, Israel, Australia, Africa, Mexico and Nortel America.

Our message at the show was frank and straight-forward - we're working through big challenges, but Nortel is open for business and committed to driving innovation.

Here's a video of our IP Powered Business Demo from MWC. This is especially good stuff for SMBs. The technology untethers workers from their desks to help make them more productive. It gives you sophisticated call routing, screening and conferencing options, and allows you to set up a single phone number and mailbox that follows you regardless of your location. Best of all, it can make any call (i.e from your cell, home phone, computer, etc.) look like it is coming directly from your office number or extension, which can come in handy if you need to call your top client - or, um, your boss - from the golf course.

Heads up - this video is a tad long, and the first half is background/narrative, so skip to the middle if you just want to see the live demo portion.

Here's a video of our IP Powered Home demo at MWC, technology that allows you to combine Internet, TV and home phone services. This allows you to do things like set up separate IP phone lines for all the kids without having to install separate phone lines. Or, you can set your home phone number to ring through to your television, MP3 player, or other devices.
