1. isdn4linux for real calls not just IVR forget it 2. capi4linux only works with cards active AND passive which do support capi at the moment those are eicon diva and cards from AVM The only passive card at the moment is the fritz card from AVM Problems here are that the passive fritz cards have some annoying thinks like it's a binary library for the capi layer which is restricted for only one card and no SMP box but you can circumvent this with the howto described at the following site http://www.quiss.org/caiviar/Two-Fritzcards-HOWTO which should enable you to use more then 1 card however i didn't manage to get this configuration to work stable as Oliver Brandt reported, or I should say it's REALLY unstable at least here. And not only with the 2 card configuration but in any configuration which means 1 card,one CPU, 2 cards,one CPU and so on so I ordered a AVM B1 PCI V 4.0 to eliminate that. Pauline Middlelink had a suggestion which would be very nice, but i think nobody is able to do it at the moment . To use the zaptel driver and to implement a real isdn4linux driver, because at the moment the isdn4linux is based on the modem- emulation of i4l and that is the reason why you have echo. This approach would solve many problems. You could use the Hisax cards not only on the outside like for the incoming calls but also for internal isdn pbx phonesets which here in europe are cheap and have a lot of nice features already builtin. For this trick see isdn.jolly.de The echo would go away, because it is digital already and I think you could count on a lower CPU usage as well. So maybe an interest group could get some funding together, to get more flexibility to the isdn side of asterisk hope this helps greetings kamido > Remember that capi 2.0 doesn't have echo suppressor routines. > Only Eicon Diva server cards have on board DSPs, that can > be enabled with Eicon custon CAPI commands. > (the great * chan_capi already do that). > > Matteo. > > Il lun, 2003-06-02 alle 12:39, Michiel Betel ha scritto: > > My Fritz paasive PCI hasn't crashed so far.... and works fine, relatively > > low latency so not too much echo.
