[ackarabas]

Hello all,

I want to see all calls that passing on the router in terms of past time. When I write "show call history voice brief" command, result is blank, 

How can I succeed the show this result?

Cisco Routers (Voice Gateways) can log CDR to a File, Syslog or Radius server.   Directions on how to configure are provided at the link below.

By default, the max number of call history table is 50 entries and the timer to age those entries out of the table is 15 minutes. Both the quantity of entries and the timer are configurable via the "dial-control-mib" command:

* dial-control-mib max-size <0-1200> -- in number of entries.

* dial-control-mib retain-timer <0-35791> -- in minutes. max is almost 25 days.

This was added back in 12.2ish (already closed the page) so you're unlikely not to have these commands available.
