Dear experts,
Please be so kind and take a look at my configurations and problem.
I need to configure Cisco 2811 (modem pvdm2-36D, E1 PRI) as RAS for dialin and dialout DDR to 250 remote locations (analog modems) with different usernames and passwords.
I managed to configure dialin where authentication is done via radius and that works flawless but I'm confused with how to configure DDR on same device.
Remote locations authenticate with radius and get their static IP addressess via radius too.
Please give me suggestions/examples.

This is my configuration for dialin and DDR dialout but it doesn't work. My idea was to make two dialer pool-member on interface Serial 1/0:15 where dialer pool-member 1 is for incoming connections (dialin) and where dialer pool-member 2 is for outgoing connections (DDR dialout) with reserved 2 B channels.
interface Loopback1
ip address 10.10.0.1 255.255.255.255

interface Loopback250

I would be very thankfull for any suggestion!

Is it possible that no one knows anything about RAS with dialin and dialout to multiple remote locations?

No very sure I understand your point here, you said that the remote dial via analog, but you want to make dialout
via the digital ?
With the current configuration you will use a B-channel, but as no modem trigger the call so you will never do analog
in the B-channel
If you want to dialout using the anallog the group-async is the interface to point as pool-member
and you will need a chat-script to provide the at command to the internal modem
