For those of you that have the IP Phone 1140E, check out the FREE web-based multimedia Interactive User Guide at
http://www.nortel.com/ipphoneuserguide
It uses a combination of video, voice, and graphics to show users of the IP Phone 1140E the capabilities/features of their phone. It could be used pre-installation for familiarization/training or post-installation as a refresher (instead of pulling out the pdf User Guide). Interactive User Guides for other models are in the process of being added.
For those of you who have not seen the IP Phone 1140E in operation, feel free to look at the guide as well.
