I use KPPP when i click on connect i hear the dialing sound then i hear the connection sound but suddenly it tells me NO CARRIER :confused:

vi /etc/ppp/options, add "debug" somewhere in the file, or just do that through kppp (I recall kppp gave you the option to turn debugging on).

Now, if you do that you'll get a bunch of lines starting with LCP/IPCP/CCP... if you can't figure it out then post the output.
