[Freeswitch-users] Estimating Call Capacity

[Cliff Wells]

A little off-topic, but since call-capacity is the subject, what are
people using to analyze their CDR's to discover this?   I'm handling
about 30k calls per day but have only a bandwidth-based guesstimate of
the peak number of concurrent calls I'm handling.

If there's an open source solution, I'd appreciate a pointer.

Regards,
Cliff
