Hello, When you are in a telephone network you'l have to dail a zero for outgoing calls. When a configured a isdn ppp connection the telephone number was 0 2301333. Linux does not seem to support this. And so I could not establish a connection. I am running the Gnome window manager. And I configured the ppp connection in "linuxconf" I was using the "Modem Lights App." and I selected isdn in that app. Greetings, Dennis Schijff The Netherlands
When you say "When you are in a telephone network", do you mean "When you are using a private exchange unit" (aka PABX) ? If so, check that it is "0" that you have to prefix the number with, as in my experience, it's usually "9" that has to be used as a prefix in Europe - I assume that .nl is Netherlands ??? If you instead mean "When you wish to call a non-local number" (the other likely interpretation of your comment), note that what has to be dialed depends on what country you are in, even within Europe. If you mean something else, please clarify your comments.
Try using rp3-config to configure your PPP connection and see if it works better. I can't imagine why a leading 0 would be stripped, as it's treated as a string not a number, but I'd be interested to know. A leading 0 is quite common in the US when dialing calls that are charged to a "calling card" so if this were really a software problem, I would have expected to hear about it before.
ISDN links use a different, modified pppd called ipppd.
please use the new isdn configuration tool from ftp://people.redhat.com/laroche/config-tool/ to configure your ISDN networking. 0 shouldn't be the problem for not getting the connection. can yu please email the output from /var/log/messages that shows how the kernel dials? That should show what the real problem is.
