[comp.dcom.telecom] Caller ID - Roll Your Own

kaufman@neon.stanford.edu (Marc T. Kaufman) (03/09/91)

{MicroProcessor Report} this month lists a recent IC announcement:

SC11210, SC11211 from Sierra Semi: Analog front-end for receiving
FSK-encoded caller ID information SC11211 also provides call progress
detection outputs.

Price: $2 in 10K quantities, in production and available.

Integrated with a phone answering machine, which already has the SLIC
and power supply and display, it shouldn't add more than $60 or $70 to
the retail price...
