Dear Experts,
I would like to set up a POTS Dial connection between 2 Cisco routers, using the modem card WIC-1AM-V2. I'd like to use this as an out-of-band connection to a remote site, if the primary internet connection fails. So, this setup will only be used in one direction, 1 router placing calls, the other one receiving calls.
Here's my config of the receiving router:
chat-script dial "" ATZ AT OK "ATX3D \T" ATS0=8 TIMEOUT 120 CONNECT \C
interface Async0/2/0
description out of band for network
no ip address
encapsulation slip
async mode interactive
line 0/2/0
session-timeout 5
absolute-timeout 10
script connection dial
login local
modem InOut
transport input all
escape-character BREAK
autoselect ppp
stopbits 1
speed 115200
flowcontrol hardwareline con 0 exec-timeout 5 0 logging synchronous login local
This config is working fine, when dialing in via a Windows Hyperterminal Dial connection. After a while of dialing I get the login prompt of the router.
Now I want to have a router placing calls instead of a Windows Server. I can't figure out how to tell a router to place calls to a POTS phone number.
Receiving router: 2811, WIC-1AM-V2, IOS c2800nm-ipbasek9-mz.124-25a
Calling router: 1841, WIC-1AM-V2, IOS c1841-advsecurityk9-mz.124-25a
Can you give me any hints?
Thanks in advance
Sebastian

The config described in this forum post is not applicable for my situation.
Any other suggestions?

You can search documentation for "configuring DDR".
Note however that dial-up modem speed is insufficient for networking, and in practice can be used only for out of band management.

Hey Sebastian,
Had the same issue, which I just managed to get it resolved.
When you insert the modem, the router will create an Async interface for it lets say Async 0/1/0
then all what you've to do is:
chat-script DialOut ABORT ERROR ABORT BUSY "" "AT" OK "ATDT \T" TIMEOUT 45 CONNECT \c
line 0/1/0
exec-timeout 0 0
script dialer DialOut
modem InOut
transport preferred none
transport input all
transport output all
stopbits 1
speed 115200
flowcontrol hardware
and to dial a the remote router all what's required is:
reverse telnet to the above line (show line to know the line number) then type atdt
Let me know in case you still get issues

Thanks gentlemen,
In fact I want to use this connection as an out-of-band mgmt connection.
It seems that using atdt commands from the modem ist the only possibility to do this.
Nevertheless it would be more convenient, I you could dial without doing a telnet onto the modem first...
