Kid lucas - If you let iCam connect long enough (up to a minute), it should either show video from the webcam or display an error message. Some of the errors are timeouts, so they can take a little while to appear.
OUAnthony is correct about the possible causes. If your office network is completely blocking UDP traffic, then you should see a Broker Connection Error message on your phone. If the network is completely blocking UDP, then there isn't anything you can do, other than get the System Administrator to change the network settings.
If the office network is using a complex form of port translation, you should see a Source Connection Error message. This case can usually be fixed by changing the network configuration on your home router. Have you tried enabling the Auto-Config Router option in iCamSource? If that doesn't work, please let me know what status message appears next to the Auto-Config Router checkbox when you run iCamSource with that option enabled.
