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: http://www.eicon.com/worldwide/products/MediaGateways/disv4bri.htm 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. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Brent Torrenga Sent: 14 February 2006 18:57 To: [email protected] Subject: [Asterisk-Users] BRI Newbie - What Hardware, PCI, in the US? 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? Sincerely, Brent A.
