TelcoBridges and call detail records
TelcoBridges TMG800, TMG3200 and TMG7800 products support the generation of call detail records in text format. They also support the ability to export call detail records to a RADIUS server for accounting purposes. Both methods can be used simultaneously.
Text CDRs are stored locally on the TMG units and must be extracted from the system either manually, or automatically.
If the network supports RADIUS, this method is preferred as each record will be sent in a timely manner to an external database for storage.
Call Details Record Generation
TelcoBridges CDRs are generated on a per-leg bases when the call is answered and when the call is terminated.
Case 1: Call Answered
Case 2: Call Unanswered
Case 3: Call Transferred
