Hi networkers,

I have an ISDN line as a backup on our router. When I wanted to test it, I saw "call rejected" message:

I found it. I removed the 'dialer remote-name" and it worked. I think it was an authentication issue because both PPP chap hostname and dialer remote-name were set under the dialer interface
