Hello Daniel, 
 
Thanks for the reply. 

The extra dictionary is already included otherwise an error is thrown and Kamailio doesn't start.
However, i realized my mistake now and you were right. I was checking for the extra attributes in a tcpdump and on radius server and i didn't had the dictionary configured on both of them. The extra attributes are in the packet but weren't being listed. 

One more question. Kamailio doesn't have a way to do a totally custom RADIUS access-request packet right? 

(Sorry if this opens another thread. I usually just hit reply on the mailing list and let Outlook create the e-mail, but it usually creates another thread and i'm not sure why). 

Thanks again. 

Cheers, 

Duarte
