One and a half years ago as I started learning about Asterisk I had an option to buy Eicon cards, but I was unsure about my ability to cope with the complexity of learning the needed bits to get started. So I bought an AVM card.... Today the situation changed somewhat: may be time for the next step.>ArminThanks a lot Aldo

E.g. for Eicon DIVA Server cards, you just set the '-x' option with divactrl or set NT-mode in the config wizard. chan_capi does not (need) to know anything about what protocol the card is doing. CAPI is independent here. Anyway, if the card is set to NT mode, you should specify ntmode=yes in the capi.conf to tell chan_capi to handle the progress better (get progress tones).> So, does the newest (which I have anyways to download for the next > release of our pbx) capi driver support NT mode?capi driver? I think you mean chan_capi? Yes it does support TE and NT mode, as well as DSS1, 1TR6, JAPAN, NI1, QSIG, 5ESS, and a lot more protocols. The card and the cards driver need to support/provide this.
