Hi Joe, In your mail you wrote that
"I've heard a few stories that reported partial success with an Eicon Diva Server card, but always with the caveat that "it doesn't work quite right" or something along those lines." I can ensure you that this is not the case. We are implementing a Diva Server card in our call centre with Asterisk - so it works perfectly on both BRI and PRI lines. You need to follow the instructions here though. http://www.eicon.com/support/helpweb/slnxen/asterisk.asp -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Greco Sent: 12 April 2006 14:06 To: [email protected] Subject: Re: [Asterisk-Users] Asterisk BRI in the USA > I dunno if it's THAT bad.

It's still similar. Out here, we get a lot of RF interference, and it turns out that BRI is actually cheaper than equivalent POTS lines with Caller-ID (a feature I require), and you can do neat stuff like having 56K dial-in with a USR I-Modem. However, CPE has always been very limited here in the States, and there was no good way to hook up direct to Asterisk. I've heard a few stories that reported partial success with an Eicon Diva Server card, but always with the caveat that "it doesn't work quite right" or something along those lines. CPE like the USR I-Modem won't deliver Caller-ID to the POTS port. Other CPE like the Motorola BitSurfr Pro is sensitive to RF noise. We were using Netgear RT338's for a number of years, but they are all burnt out now and impossible to replace (actually most CPE is virtually irreplaceable, as so few mfr's make ISDN gear anymore). And while most CPE was OK with our old POTS based phone system, almost none of it worked reliably with POTS<->VOIP gateways, such as the Sipura SPA-3000. Further, BRI has two channels, and the U interface pretty much dictates that you feed both of them to the same place. Putting them into an Asterisk box, I would lose the ability to use the USR I-Modem, for example... Despairing, I thought I might have to abandon the beautiful digital delivery of ISDN, which is stupid when you have a digital (VoIP) phone system. But: After talking with a friend up in Minneapolis, I bought an Adtran Atlas 550 off of eBay, which is a versatile Swiss Army Knife for telecom needs. With a quad port ISDN BRI and an octal FXS, it's the killer CPE device, but the best part is that it also does T1/PRI, so you can /convert/ BRI to PRI, etc. I've not actually done that just yet, though I do have a Digium T1 card around here somewhere and want to try it out one of these days. So, I can't actually say it /works/, but it's supposed to. ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.
