i have a problem with isdn connection.
i use it as the backup connection for leased line.
When i make a test call to other end router using "isdn test call" the connection disconnect after a few seconds.
i tried some solutions from TAC Case collectoin but can't solved yet.
even though i changed to another BRI interface, the line still got disconnected.
I attach some debug output, please help me to fix this problem.
With Best Regards
