Hi There, Ive managed to get a AVM ISDN Fritzcard working with debian etch (see capiinfo output below), and compiled chan_capi and got everything finished (i think). So i have: Etch + Asterisk + Zaptel + ChanCapi + Asterisk Addons + Asterisk-GUI and the chan_capi driver is loaded into asterisk: asterisk*CLI> module show like capi Module Description Use Count chan_capi.so Common ISDN API Driver (1.1.1) 0 1 modules loaded Would someone be able to help me with the config to setup the incoming calls from the ISDN card? I dont know where to start here. Thanks Simon asterisk:~# capiinfo Number of Controllers : 1 Controller 1: Manufacturer: AVM GmbH CAPI Version: 2.0 Manufacturer Version: 3.11-07 (49.23) Serial Number: 1000001 BChannels: 2 Global Options: 0x00000039 internal controller supported DTMF supported Supplementary Services supported channel allocation supported (leased lines) B1 protocols support: 0x4000011f 64 kbit/s with HDLC framing 64 kbit/s bit-transparent operation V.110 asynconous operation with start/stop byte framing V.110 synconous operation with HDLC framing T.30 modem for fax group 3 Modem asyncronous operation with start/stop byte framing B2 protocols support: 0x00000b1b ISO 7776 (X.75 SLP) Transparent LAPD with Q.921 for D channel X.25 (SAPI 16) T.30 for fax group 3 ISO 7776 (X.75 SLP) with V.42bis compression V.120 asyncronous mode V.120 bit-transparent mode B3 protocols support: 0x800000bf Transparent T.90NL, T.70NL, T.90 ISO 8208 (X.25 DTE-DTE) X.25 DCE T.30 for fax group 3 T.30 for fax group 3 with extensions Modem 0100 0200 39000000 1f010040 1b0b0000 bf000080 00000000 00000000 00000000 00000000 00000000 00000000 01000001 00020000 00000000 00000000 00000000 Supplementary services support: 0x000003ff Hold / Retrieve Terminal Portability ECT 3PTY Call Forwarding Call Deflection MCID CCBS
