Hi again, if i enter "save dialplan" in the CLI, the dialplan was saved. But if i open the dialplan with an editor, then there are entries like exten = > 222,hint,Dial in fact it must be like exten => 222,hint,Dial,Modem/g1:555 It means, the extensions.conf is damaged after saving. Is there anything i do wrong ??? Thanks for halp, Thomas.
