Hello Fellows.
I am trying PPP Callback and Callback is working fine. But the problem is
even when one B channel is UP. When I ping from CLIENT or SERVER either it
disconnects and reconnect again. I configured OSPF. Now when I try to
ping to any destination and traffic goes via ISDN , it first disconnects and
and reconnect. What should I do to correct this problem???
Below is the config and debug dialer results. On every ping it reconnects !!
Notice router is connected and one B Channel is UP.
