Here's a scenario for you:

You have a work office in NYC, but travel to your company's LA facility for a team meeting. Still on east coast time, you get into the office before anyone else and fire up your PC. You connect and use your new VoIP softphone client to send and receive VoIP calls right through your PC -- allowing people to call (and receive calls from) your regular NYC office number.

Suddenly, you feel a sharp chest pain. Right before you black out, you are able to dial 911 through your PC softphone client.

So the question is, where do the police and ambulance show up? Unfortunately, if the above scenario did happen, police would very possibly not be routed to the company's LA office.

One piece of Nortel news that slipped past me recently was our introduction of the Software Communication System (SCS) 500, a new unified communications solution targeted specifically for SMBs in the 30-500 user range (though it can scale to 1000).
