RJ-21 is a nice way to connect 25 phone lines at a time. Shortel voice switch is nifty stuff. Can terminate a bunch of analogs, handle VoIP traffic, hell, the -V models can do voicemail on board.
How much are they, I've never been able to find any information about how much the stuff actually costs.
List price on the 50 switch is $1995, 90 switch is $2995, T1k is $3495 - not sure on any of the other hardware.
