Yes, Cisco dictionary included in the dictionary of the
RADIUS server and server really send attr. that i want.
I attach a pcap file (radius3.log) of session between opensips and radius server.

Hello Denis,
Is the cisco specific dictionary included in the dictionary of the
RADIUS server too?
Also, to be able to extract a certain AVP from a RADIUS reply, you
need to make sure you have configured the server to return the
attributes you want. You can find a brief tutorial on this here [1].

Irina Stanescu
