- Somehow, I do not think that any patent can tell you how to use a
- standard telephone technology such as DID. But there are other serious
- negative considerations to DID (kept in place by the telcos because
- DID is a direct competitor to Centrex).
-
- The first is a rather steep installation charge. In Pac*Bell land, it
- is about $700 just for establishing the DID group. The second is the
- "termination charge" which essentially puts you on the hook for a
- multi-year period, even if you disconnect the service.
-
- Back when DID involved literally wiring up a switch for DID trunks,
- these charges had some validity. Now, of course, a few key strokes and
- the telco has taken thousands of dollars from you. And as a side
- benefit, those steep charges make you think twice and possibly
- consider Centrex as an alternative. Telco makes much more money from
- that in the long run.
