With CT1 you can still do DOV ISDN (56K Voice ISDN). That's home I'm
connected right now.

At the present with CT1 you can not do Outbound calling or have
Called-Station-ID or Calling-Station-ID information. Also PRI gives much
better debug info when looking into connection problems as you get the D
channel to play with and monitor.

CT1 will give you up to 24 lines per T1. PRI W/O NFAS will give you 23
Lines.
