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 User-Name = "41001" User-Password = "."

Delaying request 0 for 1 seconds Finished request 0 And this is part of my radcheck table on radius server: +----+-----------------------------+---------------+----+-------+ | id | UserName | Attribute | op | Value | +----+-----------------------------+---------------+----+-------+ | 1 | 41001@localhost.localdomain | User-Password | := | 1001 | | 2 | 41004@localhost.localdomain | User-Password | := | 1004 | +----+-----------------------------+---------------+----+-------+ Could anyone tell me how to config b2bua and radius to make them work fine?
