We are not even 50% compatible - Cisco boxes send at lest 15 more attributes.

That's the reason why to send only real h323-xxx-time values.
If you find missing h323-setup-time that means no signalling channel has been opened.
If there is no h323-connect-time, that means no Connect message has been received (call has not been answered).
You can then show your customer:
"Look, the phone was ringing (h323-setup-time present), but the remote party did not answered (no h323-connect-time)
or gateway terminated the call (some specific h323-disconnect-cause). The phone was ringing for
(h323-disconnect-time-h323-setup-time) seconds."
or
"Look, our gatekeeper received only admission request (ARQ) and it has been confirmed, but your endpoint
did not open signalling channel (no h323-setup-time, no h323-connect-time)"
Earlier, when all h323-xxx-time has been sent - these were just filled with some
useless values, like copying h323-disconnect-time to h323-connect-time and h323-setup-time.
This way, some call flow info has been lost.
With some radius server, it is easy to replace missing attributes, like (FreeRADIUS):
'%{h323-connect-time:-%{h323-disconnect-time}}'
that means "take h323-connect-time if it is present, h323-disconnect-time if not".
