I have problems with users who use windows '98 and call into the cisco3640 with ISDN and they should be called back with the callback-dialstring. The can call in, that's no problem but if the router calls back the call has been disconnected. I have tested the callback functionality with my computer (windows 2000) over ISDN and that works fine.
Here below you will find the config file and debug information. Please who have useful tips for me???
