how to config b2bua and freeradius together?

[zhangshuai]

Dear all,

I intend to make use of b2bua-1.5.0 to do prepaid together with freeradius-1.0.4 and ser-0.8.14. I use this scenario to set up a call:


          -----
          |UA2|
          -----
            ^
            |
            |6
            |
          -----     5      -------    4    ---------------
-----  1  |   |<-----------|     |<--------|             |
|UA1|---->|SER|     2      |B2BUA|    3    |radius server|
-----     |   |----------->|     |-------->|             |
          -----            -------         ---------------



Now I found that b2bua can talk to radius server directly, without using radius client. However, I received "access reject message" from radius server when I tried to initiate a call. Here is the debug message on radius server:

rad_recv: Access-Request packet from host 218.97.252.38:1024, id=2, length=71

And this is part of my radcheck table on radius server:

+----+-----------------------------+---------------+----+-------+
| id | UserName                    | Attribute     | op | Value |
+----+-----------------------------+---------------+----+-------+
|  1 | 41001 at localhost.localdomain | User-Password | := | 1001  |
|  2 | 41004 at localhost.localdomain | User-Password | := | 1004  |
+----+-----------------------------+---------------+----+-------+

Could anyone tell me how to config b2bua and radius to make them work fine?

Thanks in advance.
