I'm notoriously flaky with dial-up, but still interested. I haven't got your earlier e-mails. Have we got both configs. Presumably, for some reason, RouterB doesn't recognise that it is already connected to RouterA so it dials a second channel for the return traffic. Are the dialer-map statements spot on. Have you tried using ppp sent username?
Let us know the outcome.
