As you all know I had problem with MSISDN <-> Framed-IP-Address mapping with cisco NAS.
Finally I found problem resolution.
Those two command are necessary for cisco NAS to transmit Framed-IP-Adress after IP address is assingned to client:
radius-server attribute 8 include-in-access-req aaa accounting delay-start
Both command issued in general configuration section.
