===========================
On the CSACS server I have the following selected under Group:
Cisco IOS/PIX RADIUS Attributes
[check] [009\001] cisco-av-pair
IETF RADIUS Attributes
lcp:callback-dialstring=5552000
[check] [006] Service-Type
Framed
[check] [007] Framed-Protocol
PPP
All the other options are unchecked and I have Authenticate
Using RADIUS (Cisco IOS/PIX) under Network Configuration.

Hi,
I am trying to configure my radius server (ACS) to provide the
isdn callback string to the router.
I receive the following:
cisco AVPair "lcp:callback-dialstring=384800" not applied for
multilink
cisco AVPair "lcp:callback-dialstring=384800" not applied for ip
is this normal? Have I forgot something ?
the isdn link is established/authenticated but no calllback.
Help,
Zal
