Viewing Gateway CDR History

You can view historical Call Detail Records (CDR) of Gateway calls in the Gateway CDR History table. The table displays the last 4,096 CDRs. CDR history information is stored on the device’s memory. When a new CDR is generated, the device adds it to the top of the table and all existing entries are shifted one down in the table. If the table has reached maximum capacity of entries and a new CDR is added, the last CDR entry is removed from the table.

● The CDR fields in the table cannot be customized.
● If the device restarts, all CDRs are deleted from memory and from the table.
● You can mask (hide) values of certain CDR fields, as described in Masking PII in CDRs.
➢ To view Gateway CDR history:
■ Web: Open the Gateway CDR History table (Monitor menu > Monitor tab > VoIP Status folder > Gateway CDR History).

■ CLI:
● All CDR history: 
# show voip calls history gw
● CDR history for a specific SIP session ID: 
# show voip calls history gw <session ID>
