[Asterisk-Users] Polycom 600 phone

[Chris Gamble]

>From their website, the key difference between the polycom 500 and 600 phones is the number of "lines" they support. What does this mean in terms of asterisk? Do I have to have a seperate extension for each of these lines or ? 

Also, slightly off-topic, how does the 500 POE "optional" cable work? Is this similar to have a power box on your desk, or is just a differently configured CAT5 cable? 

And finally, being poor as we are, are the cheaper (ie non-400$ each) Polycom's usable?

Thanks,
