I'm trying to set up dial on demand routing between (2) cisco 1841 routers with PPP authentication. Both routers have a modem connected to the AUX port and both modems are connected to a POTS line. I want both routers to be able to initiate a call. Currently the modems are connecting but it appears that I'm failing PPP negotiation. Any help would be greatly appreciated. Below are running configs of both routers.

The async interfaces needs IP addresses or ip unnumbered, to begin with.
If still trouble, send output of debug ppp negotiation.
