I have connected two 805 routers on a PSTN line . The remote rouer does not allow calls to be authenticated on it. The line gets disconnected

Please supply configs or output of "debug ppp negotiation".

Hi Please find the runn config. The modem handshakes holds the line and then disconnects.

It seems you have a modem configuration problem.
Try removing modem autoconfiguration from line 1 and configure the modem manually using a terminal with the following initialisation string: AT&F1&W
This is the "harware profile" initialisation string for usr modems.

We need to see the following debugs on both the routers:
deb chat / deb modem / deb ppp nego
Try the following modemcap:&f1s0=1&c1&d2&a1&w on the usr with dip switches 3&8 down & rest up.
Thanks, Mak.
