Hello JP,
I see couple of things missing on your configuration.
Under R3's int dialer 1, add "dialer remote-name R5", and "dialer pool
1".
Since you didn't have dialer remote-name R5, ppp authentication was
failing.

In the below output, it is disconnected from R3.
Do you have any idea what at R3 would disconnect the call as soon as
line is
up. The call lasted only one second.
