Sorry to mention this, if it is obvious, but a dialer string is not required
on both routers in order for a connection to be made ... the debugs
mentioned are from R5, which has a dialer string ... all in all, this is a
simple configuration ... have you tried to shut off and restart your
simulator? I have a Black Box ISDN simulator that needs a good reboot every
month or so - maybe a memory leak in it's core logic, dunno ... this should
work fine, except the extra dialer map statement on R5 pointing to itself
... remove that and try it again
