We have gone with the WIC-1AM modem module for our console routers. However, upon dialing in, I get a quick hangup by the WIC-1AM, debugs show the following:
*Apr 10 08:35:29.775: Modem (0/0) DCD Asserted
*Apr 10 08:35:29.799: Modem (0/0) DCD UnAsserted
My config is here:
router#sh run | begin line aux 0
line aux 0
exec-timeout 30 0
password 7 XXXXXXXX
script reset sportster
login authentication modem
modem Dialin
modem autoconfigure discovery
transport input all
stopbits 1
speed 300
flowcontrol hardware
line 0/0/0
stopbits 1
speed 115200
flowcontrol hardware
Thanks in advance for any suggestions!!

Hi Dan,
WIC-xAMs are sensitive to line voltage. So you might want to try a different phone line on it and see how that works.
By the way, if you are reverse-telnetted into the WIC, and now you dial in, do you see RING ?
Also try to dialout from reverse-telnet mode and see if that works.
Thanks and Regards,

Thanks for reply. I was able to do as you suggested, using atdt command to dial my desk phone, and observed RING, when an incoming call was placed. Still investigating, but no progress yet.

The 'Unkn protocol' at the top may be the key.
