Hello, while the AVM Blue!FRITZ ISDN access point in combination with the AVM Blue!FRITZ USB dongle and the AVM software package is working well in the Microsoft Windows world, I can NOT get the same hardware to work satisfactory under Debian Linux. I have tried in combination with Debian EtchnHalf and recently also under Debian Lenny. As PBX system I do use Asterisk with chan_capi to connect to ISDN and Ekiga as softphone. Bluetooth connectivity: The access point is found, pairing works, capiinit start also successfully loads AVMs capi driver Asterisk integration: chan_capi is loaded, I can receive and place calls, BUT THE AUDIO QUALITY IS VERY BAD (which makes the set-up useless). Looking at the capi debug messages, the log is flooded with messages 'b3count is full, dropping packet' during a call/conversation. AVM does not provide support and just comments "the implementation of the Blue!FRITZ driver under Linux is an external open source project for which we do not provide support. The scenario should work fine under Windows". Asterisk specialists state that this message originates from the card/driver and would be thrown when the data packages asterisks sends to the card/driver are not confirmed back (per CONF). Unfortunately, they are not familiar with Blue!FRITZ and can therefore not further comment on how this problem might be solved. Can someone here advise what to do / try?? I would really like to stay with the bluetooth solution as my machine has no more PCI slot for a build-in card available.
