I noticed my HQ office's lines could conference in multiple parties (by pressing the
cradle & call additional parties) & it uses sort of PABX (phone four-digit extension
But with direct Telco lines that we lay at our remote office, I can't do this & even
with the teleconf facility, it won't work.
Is conferencing in multi parties a line function or the equipment function? I'm
guessing it's a line function
Does Telco support direct phone lines that support multi party conferencing?
If I don't plan to upgrade /subscribe to this feature (by paying more), is there
any teleconf equipment or software or hardware that will enable this function
at our remote office?
