Dial on demand routing between (2) 1841 Routers

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.

Re: Dial on demand routing between (2) 1841 Routers

The async interfaces needs IP addresses or ip unnumbered, to begin with.

If still trouble, send output of debug ppp negotiation.
