Hey Mani,
I spent some time on your first item A - this was a good exercise for me...
R2---------ISDN----------R3
R2 configured as callback client, R3 as callback server...

Did not DISCONNECT and call R2 back...
So it appears the "class" component of the dialer map is required. I couldn't find a good debug command to detail ppp callback. Anyone have any ideas on this?
