While many of the explanations given can be construed to be true, but the botto
m line is: the 'ppp authentication' command instructs the configured router to
authenticate the remote router, period. The 'callin' option is what commands th
e configured router to authenticate the remote router when it happens to be the
called router. The router configured with 'callin' will not challenge the remo
te router when it happens to be the calling router. Whether or not the configur
ed router itself is challenged, of course depends on the other end...

i believe all isdn routers support 2-way chap, since companies like to
adhere to RFC
