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.

Re: [Asterisk-Users] ISDN4Linux + Asterisk and Europe
Hallo Klaus-Peter, i am currently working on a zaptel BRI driver which will support the very nice (also nicely priced) hfc-pci based cards and the multiBRI cards. the driver will support TE and NT mode. Any timeplan? I'm considering buying a diva server card with echo cancellation but I'd much prefer your solution :-) Gruss, Chris ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] ISDN4Linux + Asterisk and Europe
There has been a lot of discussion about ISDN BRI on the list - a search will turn up plenty of discussion! You're right about there being a lot of ISDN cards available that are certified for use in Europe. They fall into two categories - active and passive. Passive cards are cheap and generally operate through ISDN4linux and asterisk's chan_modemi4l. The reported disadvantages of this approach are: - delay during calls - echo (it's disputed what the cause of it is but it's a bit of a nuisance) - call tones don't follow PSTN patterns. The active cards (AVM is the major supplier, I think) are better. If you get one with a CAPI interface then you can use the asterisk chan_capi driver. I haven't any experience of this type of card - maybe someone else can provide feedback.
