As a national broadcaster, ISDN is definitely NOT cost effective
compared to IP based transport.
I don't disagree. I'm simply suggesting that digital telephony of one
form or another is more reliable and little latency. And, in certain
circumstances cheaper than IP.
Our friend at the Bible college didn't say whether he's talking about
long distance (as in telephone charges) or not. Although, there's an
organization here in Dallas that uses ISDN for remote conferences with
NY. I do know that they have an unlimited long distance plan for their
ISDN line and so the total cost per month runs them about $130.00 per
month for the ISDN line and the long distance charges. I don't know what
they pay on the NY end for the ISDN line they dial into. I do know they
always initiate from this end because they couldn't find unlimited long
distance for their ISDN line in NY at the time they set it up.
Also, since the connection always goes to a single location, that
reduced their costs as well.
