I have seen and tried this as well as several other configs and they never
seem to work well or consistently. Either the line flaps, or you have to
shut down interfaces in a certain order and bring them back up again to get
it to reset properly. Dialer interfaces won't work right or any number of
other weird things. At any rate, after getting tired of trying to get it to
work in any kind of consistent manner I finally broke down and rented an
ISDN simulator for 200.00 a month.
If you get this to work nicely and consistently I would be interested to
know it, as everything I have tried so far makes the whole aux port back to
backfor DDR very tiring to use.

Here are working configs compliments of Brian Dennis:
Below is a working config for AUX-to-AUX dialup using a
rollover cable. R1
can call R3 using these configs.
