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 Acct-Status-Type = Start Service-Type = IAPP-Register EAP-Key-Name = "\000\000\000\310" Error-Cause = Invite Attr-55 = 0x4d343460 Sip-From-Tag = "1e356213" Sip-To-Tag = "c73cd9ce3e9841fbb233a3f65b14b5ee" Acct-Session-Id = "NDgzODg4NGRhYzMwYTQ0MjBmNTlmNTlmNmVkM2U0ZGE."

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.
