accounting with opensip and radius;error-cause=invite

[happyeveryday1025]

Hello:
I am using opensips1.6.4+freeradius2.1.10+radiusclient0.5.6 to do accounting when two X_Lite registered in opensips make a call,Now I define the attribute "Contact"as followed:
ATTRIBUTE  Contact 100 string
 
When I make a call, the radius server has a response,
  rad_recv: Accounting-Request packet from host 192.168.118.39 port 50962, id=179, length=288

You can see that there is some error information ,such as error-cause=invite;and when the call is terminated,the opensips receives a bye message,but the radius server has no response,can anyone help to figure out the error please?Thank you very much.
