Start and Stop records

The Ascend_Global_Call_Id attribute in the Start and Stop records for SS7 VoIP and data calls is for call-logging only, not RADIUS, and is reported only when the global call ID is available.

The TAOS unit sends Stop records for SS7 calls that are cleared or rejected at the SS7 IPDC layer. Those calls do not have Start records, because they are never routed to host cards.

Disconnect cause codes

The following set of disconnect cause codes reports the cause of termination for calls that are cleared or rejected at the SS7 IPDC layer. These codes are based on the cause codes defined by ITU-T Recommendation Q.850, Usage of Cause and Location in the Digital Subscriber Signaling System No. 1 and the Signaling System No. 7 ISDN User Part. This group of cause codes begins at offset 800.
