    isdn4k-utils-3.0beta1's ipppd (Or ANY ipppd) needs a short patch to
    allow for the extra-version in 2.2.0-pre?. It chokes on the pre?, and
    defaults to 2.0.x. Look into sys-linux.c in the ipppd source and comment
    out the following code in the decode_version function:

    if (*buf != '\0')
    *version =
    *modification =
    *patch = 0;

    This will allow you to dial in. This is NOT a problem with the kernel ISDN
    code, but a buggy version decoding.
    (I'm currently using an unpatched 2.2.0-pre9 with a modified isdn4k-utils
    to dial in, so it definately does work)

    When I shop for hardware I always look for the "Designed for Windows 95" logo.
    I really thank Microsoft(TM) for encouraging manufacturers to label their
    products this way, so I know what to AVOID.

    I stick to quality software:

    Linux 2.0.36 | IBM OS/2 Warp (TM) v4.0
