Parallel posting this to both CDRTool users and OpenSER users, so apologies to members of both. I have installed the latest version of CDRTool and running it with OpenSER 1.1.1 for the time being. When looking at the tcpdump of the records leaving the OpenSER server via radiusclient-ng I am viewing a few 'Unknown Attribute' statements. Ex: Accounting Status Attribute (40), length: 6, Value: Start Service Type Attribute (6), length: 6, Value: #15 Unknown Attribute (102), length: 6, Value: Unknown Attribute (101), length: 6, Value: Username Attribute (1), length: 26, Value: +15552221111(a)x.x.x.x Calling Station Attribute (31), length: 24, Value: sip:+15552221111@x.x.x.x Called Station Attribute (30), length: 32, Value: sip:+15553334444@x.x.x.x Unknown Attribute (107), length: 35, Value: Accounting Session ID Attribute (44), length: 14, Value: 0d487415(a)mysipserver.com Unknown Attribute (104), length: 10, Value: Unknown Attribute (105), length: 7, Value: Unknown Attribute (103), length: 6, Value: Unknown Attribute (214), length: 15, Value: Unknown Attribute (215), length: 6, Value: Unknown Attribute (216), length: 32, Value: Event Timestamp Attribute (55), length: 6, Value: Thu Mar 27 11:01:23 2008 NAS IP Address Attribute (4), length: 6, Value: x.x.x.x NAS Port Attribute (5), length: 6, Value: 5060 Accounting Delay Attribute (41), length: 6, Value: 00 secs I have looked into the dictionary.ser and each of the Attributes are defined and the dictionary file that is defined in radiusclient.conf has the $INCLUDE dictionary.ser statement. Any hints, ideas or links would be appreciated. -- -- Krom kyle.romulas(a)gmail.com
