Hi, Anybody have lots of experience with PCI ISDN cards and Asterisk? I'm thinking of getting a BRI in my house to deliver more advanced signaling to my PBX (yes, I'm a geek :-)) but I've never played with isdn4linux. Is there any particular BRI card that works better with Asterisk than any other? Also, can the BRI interface cards participate in conference, etc., since they aren't a Zaptel interface? Thanks, M

I use this setup and have found minimal echo problems and quite good performance all round... The card cost me ?3 off ebay.. you really can't beat that.. :)> > Also, can the BRI interface cards participate in conference, etc., since > they aren't a Zaptel interface?I haven't used conferencing but I believe you can load the ztdummy emulator to get it working..

The least-supported in Linux seems to be "National" ISDN (NI-1, NI-2), what I get here in North America. I'm guessing you're in the same boat, right?> Is there any particular BRI card that works better with Asterisk > than any other?So far, I've tried Dynalink, HFC-S, and Fritz! AVM PCI.. none has worked correctly with Linux/Asterisk, and I suspect it's an i4l problem with National ISDN. The incoming Caller-ID is always zero, even though I can see the text right there in the SETUP messages. So far, I haven't been able to complete a call. Others have had better luck with the CAPI drivers instead of i4l, but most CAPI drivers are binary only and support only EuroISDN. Klaus-Peter Junghanns suggested the "Eicon Diva Server BRI" active card as having Linux CAPI drivers with NI-1 support. Those cards are not cheap.. $520 at TheNerds.net. The Passive BRI cards are dirt cheap, under $5 on eBay, so I'm still motivated to make them work.> Also, can the BRI interface cards participate in conference, etc., > since they aren't a Zaptel interface?I could be wrong, but I read one reference that said you can have conferences so long as there is one Zaptel card in the machine somewhere (for timing?). You can use other cards for your trunk. I'm sure someone can jump in and correct me. In any case, it sounds like we're trying to do similar things. The new low prices on ISDN BRI makes them very attractive here. I especially like getting the CallerID data before the phone rings, and being able to bring up a call in milliseconds. Asterisk is a great match to ISDN BRI, since we are only allowed one phone handset per SPID -- two total. Deploying more phones throughout the house/office really begs for a small PBX like Asterisk and some SIP phones. That's the vision, anyway. -Steve
