[Asterisk-Users] BRI Newbie - What Hardware, PCI, in the US?

[David Waugh]

IMHO, the Diva Server BRI range of cards are worth considering. The Diva Server 4BRI card is an active card that can do echo cancellation, automatic gain control etc. The 4 port card costs similar to 2 single port cards so there will also be room to expand if you need it.

More information can be found here:

It is well supported by using the Eicon Diva CAPI Driver and the Chan-capi-CM driver from Melware. Not the cheapest but you will get good quality results. I have one running here.

We are looking to lose the TDM400P in favor of an ISDN-BRI solution. This
should get rid of static on the line (at least any static generated by our
half of the circuit), right?

I am a total virgin to ISDN. I understand that we need two BRI circuits to
provide four voice channels, and that the hardware to speak to the BRI
circuits can be passive or active, with the active type being much more
preferred due to it's echo cancellation abilities.

I do not even know which brands/models to consider that are out there. Given
that we are in the US, and want to use BRI to improve sound quality (no
echo, no static), what would be some good cards to look at? I hear a lot
about BRIStuff, which I think is used on the Junghanns cards (like the
quadBRI PCI ISDN), using the CAPI channel. Are those the Cadillac of ISDN
cards?
