ISDN cards and TA's are like modems, but 5 times faster. They require special
telephone lines, which cost a little (or a lot, depending on your phone
company) more than normal phone lines.
ISDN calls are usually (in USA) charged by the minute, even for local calls,
but this varies from state to state. In California, it's free for home use
during off-peak hours, and $0.01 or so per minute during business hours.
If you're quite nearby to someone you connect to constantly, you can
sometimes order Centrex service, and get free calling always.
Businesses seeking fulltime connection are often better served by
56Kb/sec Frame Relay instead of ISDN, as it's flat rate. Consult
Steve Neil's excellent page of
Frame Relay Resources for more info.

To do CTI, you need hardware (either a computer with a built-in ISDN
interface, or one or more plug-in cards) and software (commercial or custom).
In between, you need to use an API (CAPI, WinISDN, TSAPI, MVIP, or proprietary)
and possibly middleware (Visual ISDN, etc.). You might use Windows,
or for big applications, UNIX or Windows NT. Check my software and hardware
pages for those.
