The point is Channels must be allocated somewhere and someone has to pay
for them. A minimum of $19.95 per channel is a quite a deal when
considering how much it would cost you to have an actual ISDN PRI
installed on your end.  The provider has to pay for all the channels
they have into the PSTN networks although they do get discounts and are
installing OC3 connections to the PSTN networks does not mean they don't
pay for all those connections each month.

Just some points to ponder before wanting free unlimited connections.
This will never be a reality even if you use toll bypass by connecting
directly to another sip or IAX Phone system. You are limited by your
bandwidth you have and what the other end has for a connection.  There
is also compression but you do loose quality to gain more connections
that is a sacrifice you choose to make as far as quality. The bottom
line the more Bandwidth you need the more it will cost you.  NOTHING is
free.

Thanks for  listening,
