[Serusers] b2bua + SER + RADIUS

[Lucas Aimaretto]

I've got some doubts with b2bua. If any body knows, I'd like 
to ask the following ..

This is the configuration.

SER: 			192.168.1.252:5060
b2bua:		192.168.1.253:5065
Radius-auth:	192.168.1.253:1812
Radius-acct:	192.168.1.253:1813
Tel SIP:		192.168.1.178:11005

(Note: I've SER, RADIUS and B2B running on the same PC. To 
identify each service, my linux has 2 IP address, 
192.168.1.253 and 192.168.1.252)

I've sniffed the net ... and got this.

Which is, basically ...

TEL SIP		B2B		SER		RADIUS
   |------(1)----->|           |             |
   |------(2)----->|----(3)--->|             |
   |               |<---(4)----|             |
   |<-----(5)------|           |             |
   |------(6)----->|           |             |
   |               |----(7)--->|             |
   |               |-----------+--(8)------->|
   |               |<----------+--(9)--------|
   |               |<---(10)---|             |
   |<----(11)------|           |             |
   |-----(12)----->|           |             |

Well, the Tel SIP got registered at the SIP SERVER (SER), as 
usual, ... and I have authentication, with radius, configured 
in SER to be used at REGISTER time ...

[...]

 if (method=="REGISTER")
                {
                         log(1, "REGISTER message received\n");
                         # Lo siguiente es para auth con RADIUS
                         if (!radius_www_authorize(""))
                         {
                                 www_challenge("", "0");
                                 break;
                         };
                         save("location");
                         break;
                 };
 
[...]
 
QUESTION: Why is B2B talking to RADIUS instead of SER ??? 
Should not be SER the one talking to RADIUS ???

If it is really obvious, do not get mad at me ... ;-)

Regards,

Lucas
