Sounds like one pool is 192.168.1.0 /24 and the other is 192.168.20.0 /24
.... no overlap.

Are you using the DHCP-proxy feature fro the dialers?

Seems to me that the dialer interfaces should report a giaddr in the
192.168.20.0 /24 range which will cue the server to hand out addresses from
the 192.168.20.0 /24 scope. DHCP requests withoput giaddr on the local
wire are given 192.168.1.0 /24.

What DHCP server? IOS?

You could alternatively use a local pool in the router for the BRIs.
