Unfortunately although the Quintum supports SNMP it does not show any call information. The SNMP traps will show the error log information as seen in the Quintum GUI, i.e. red errors for severe, amber for warnings, and green for information.
The simplest way to check the number of calls going through the unit is through the CLI. Type
> ch calls [RETURN]
at the root prompt, this requests the call information from the Call Handler (CH).
I can supply you with the MIBs if you email me at: email@example.com
Hope this helps.
