How to monitor VoIP traffic (Cisco SNMP MIBs/Monitoring Software)

[e-alvarez]

Hi all,

I?m new to VoIP, and I want to monitor the traffic on the router genrated by voice calls.

Most of my routers are 1760, with a few 3660.

The router/ios/cards combinations are as follows:

1760/c1700-entservicesk9-mz.123-9.bin/VIC-2FXS=

3660/c3660-is-mz.123-13.bin/VIC-2FXS or E1/PRI

Does anybody know what CiscoSNMP MIB/Software combo to use?

We have HP OPen View for monitoring the rest of the network, but could use other software as well.

Any help will be much appreciated.

Regards,

Eduardo

Here are a few MIB objects you might want to look at:

CISCO-DIAL-CONTROL-MIB - Poll first to get all the call history records.

CISCO-VOICE-COMMON-DIAL-CONTROL-MIB - Common information for all types of

call legs. This is polled next.

CISCO-VOICE-DIAL-CONTROL-MIB - Has tables for getting more information on

Telephony and VoIP call leg.

CISCO-VOICE-ATM-DIAL-CONTROL-MIB - For getting more information on VoATM

call leg.

CISCO-VOICE-FR-DIAL-CONTROL-MIB - For getting more information on VoFR

call leg

CISCO-PROXY-CONTROL-MIB - For getting more information on Proxy call leg
