[asterisk-users] Digital Phones

Yeah, they still sell the phones:

&prod_id=8593&locale=en-US

I looked around and I can't find that kind of multiplexer. You'd looks like
you would need a small digital PBX since you need to be able to define
stations and a dial plan.

Still?

(Is Nortel even making these phones anymore? I thought they spun off
their telephone set division -- anybody heard of Aastra? ;) )

Is this anything like a channel bank, only for digital phones?

Can you suggest any examples?
