Obtaining DDR Number from RADIUS Server


I was wondering whether it is possible to obtain dialout numbers for DDR routing from a RADIUS server rather than them being stored in the configuration on the router??

I have a 3745 with a PRI card centrally, and a number of 1721's with BRI cards at the remote ends. The 1721's are all configured to dial the central 3745. Currently, the 3745 is configured with dialer map's for each of the remote ends, but, as these remote end telephone numbers can change quite frequently I'd like an easy method to keep these numbers updated.

Do you mean for the 3745 to callback to the 1721's? If so, then yes, it's discussed here:

Not looking to do callback, but if the central site needs to originate a call to the remote site, then I'd prefer it to obtain the number from the tacacs+ server. It's to simplyfy administration as the numbers will be changing frequently and I'd rather have people change the number on the tacacs+ server than on the router itself.
