CDR and unanswered calls

[jseynaeve]

Hello all,

I have a question regarding unanswered calls in the CDR records. Sometimes they do show up, other times they don't.

Any light on how CUCM decides to create a record or not is welcome ...

Cheers,

Jan.

Hi,

I think you should activate the CDR Calls with zero duration, in order
to log "not connected calls"

Extract from CUCM Help :

CDR Log Calls with Zero Duration Flag:   This parameter enables or
disables the logging of call detail records (CDRs) for calls that never
connected or that lasted less than 1 second. Cisco CallManager logs
unsuccessful calls (calls that result in reorder, such as might occur
due to a forwarding directive failure or calls that attempt to go
through a busy trunk) regardless of this flag setting.

haha, indeed, gotta love the service parameter section ;-)

Thx mate,
