PRI. A voice T1 will require at least 1 ring, and possibly a bit of time
for any DID or ANI information to be passed via DTMF where as PRI passes
the data out of band and the "ring" is really out of band also. This
allows your application to answer on 0 rings instead of 1 ring. This
alone made some of our clients unhappy as we passed certain calls to a
different computer that required 1 ring also to answer.
Also in some states like where I am, you get a break on the taxes for a
PRI due to the fact that a PRI is considered a bulk purchase as opposed
to 24 line items. I don't understand why, but that is what our rep told
us.

I know there have been a few people here work on them, but I think they
all where to be used inhouse by that company.

What do you expect to get from them? From my limited knowledge, and
their limited documentation, it didn't look very useful for what
asterisk needs. I may very well be wrong here and would love to hear
what you think it would contribute.

"what's up..." is a very open question. If you are referring to
why
isn't X supported, it is probably because no one with X has written the
driver or it isn't supported by the linux kernel. If you are referring
to why do you have to pay for Dialogic support, Dialogic has not open
sourced their drivers and there fore you need to use the non-GPLed
version of asterisk to support the non open sourced driver. If you have
a different verion of the "what's up" question, just ask a more
directed
question.
