I have a PRI on a 3660 for RAS. Call back works perfectly for my modem (Xircom), but an on-board modem on an IBM laptop does not work.
The router calls back to the IBM which answers the call only to have it dropped by the router almost immediately. I suspect that the router's modem trains in to the IBM when it dials, but the IBM does not train in to the router when it dials back. Am I correct? If so, is there a work-around, or what is the problem?
Thanks.
