RE: [Serusers] b2bua + SER + RADIUS

Dear Lucas,

which radius server you are using ?

iam using the free radius server - 0.9.3

and how are you maintaining the billing server

my radius database radacct is haveing the following

coloumns

+-------------------------+----------------------+------+-+ | Field | Type | Null | Key | Default | Extra | +-------------------------+----------------------+------+-+ | RadAcctId | bigint(21) | | PRI | NULL | auto_increment | | AcctSessionId | varchar(255) | | MUL | | | | AcctUniqueId | varchar(255) | | MUL | | | | UserName | varchar(64) | | MUL | | | | Realm | varchar(64) | YES | | | | | NASIPAddress | varchar(15) | | MUL | | | | NASPortId | varchar(50) | | | | | | NASPortType | varchar(255) | | | | | | AcctStartTime | datetime | | MUL | 0000-00-00 00:00:00 | | | AcctStopTime | datetime | | MUL | 0000-00-00 00:00:00 | | | AcctSessionTime | int(12) | YES | | NULL | | | AcctAuthentic | varchar(32) | YES | | NULL | | | ConnectInfo_start | varchar(32) | YES | | NULL | | | ConnectInfo_stop | varchar(32) | YES | | NULL | | | AcctInputOctets | bigint(12) | YES | | NULL | | | AcctOutputOctets | bigint(12) | YES | | NULL | | | CalledStationId | varchar(50) | | | | | | CallingStationId | varchar(50) | | | | | | AcctTerminateCause | varchar(32) | | | | | | ServiceType | varchar(32) | YES | | NULL | | | FramedProtocol | varchar(32) | YES | | NULL | | | FramedIPAddress | varchar(15) | | MUL | | | | AcctStartDelay | int(12) | YES | | NULL | | | AcctStopDelay | int(12) | YES | | NULL | | | SipMethod | varchar(50) | | | | | | SipResponseCode | smallint(5) unsigned | | | 0 | | | SipToTag | varchar(255) | | | | | | SipFromTag | varchar(128) | | | | | | SipTranslatedRequestURI | varchar(255) | | | | | | SipUserAgents | varchar(128) | | | | | | SipApplicationType | varchar(255) | | | | | | SipCodecs | varchar(255) | | | | | | Timestamp | bigint(20) unsigned | | | 0 | | | DestinationId | varchar(255) | | | | | | Price | varchar(255) | | | | | | Rate | text | | | | | | Normalized | enum('0','1')

and how did you configured b2bua with the radius

and the ser exactly?

this is configuration.

could you able to establish the communication

properly?

REGISTER:

No problems here, because the telephone talks to SER, SER talks to RADIUS (see ser.cfg) and the phone is registered. Easy. When TEL sends and INVITE, SER forwards the INVITE to B2BUA, which sends an Authorization Request to RADIUS. OK here, because B2BUA sends and auth req with calling-station-id and called-station-id, which is good, with both acct-start and acct-stop. Now, upon the BYE message, B2BUA is not sending the Acct-Session-Time for doing billing. Which is not good. Any ideas ?

Now, it this the correct way of doing this ?

Thanx.
