No, That looks to me like straight after authentication succeeds then the
caller is taking down the ppp link.

Can you enable ppp debug (i.e. add debug to your ppp options) and get more
detail on what's happening between successful authenticaton and LCP being
brought down?

FWIW, my ut feel is to put an IP negotiation conflict high on the suspect
list.

Urgh, any chance of getting the clocks synchronised (the closer the
better ;-)?

Wild guess: the caller first is "Sending CALL_CLEAR_REQUEST" and then the
"CALL_DISCONNECT_NOTIFY RECEIVED" is a log of receiving an ack of the
clear request.

HTH,
