I have set up systems with 8 conversations over a 128 Kb/s ISDN line.
VoIP? Otherwise that is just two B-channels, and they can (to my
knowledge) carry one conversation each?
Voice over IP or the same data over a serial link. I used a device from
a company that used to be called "MCK" (I don't recall the new name).
They have a line of PBX extenders, which could work over serial lines
(ISDN, fractional T1 etc.) or IP. They had models that supported 8, 12
and 24 extensions and it was possible to configure for more lines than
supported bandwidth, in which case not all extensions could be on a call
at the same time (blocking). I often set up the 8 port model over a 128
Kb ISDN line. A 12 port model could be set up for 10 non-blocking
extensions or 12 blocking, over 128 Kb, but I haven't done either of
those configurations. They also have a single extension model that
contained a regular dial up modem and used an ordinary phone line.
These devices allow for PBX phones in a remote location and work with
various PBX makes such as Nortel, Avaya etc.
