Monitor number of phone lines in use

[nmoore1978]

Hello,

My voice gateway has three voice T1's in use.  Two of them are for outgoing long distance and incoming toll free calls (total of 48 ports).  The other is a PRI for local calls with 23 ports.  How can I monitor the usage of active ports (calls) on these circuits?  I know that I can use "show voice call sum" to show the status of the ports.  Can I monitor this via SNMP somehow?

Any help is greatly appreciated.

Thanks,

Nick

I forgot to mention that I currently use Nagios for monitoring.  So I would be looking to monitor the number of active calls and then send an alert when it reaches X number of active calls.  But that part is more of a Nagios config than Cisco.  Basically I'm just looking for snmp command of current active calls. 

Thanks again.

Hi Nick

Try SNMP OID

1.3.6.1.4.1.9.10.19.1.1.4.0

Shoudl return the number of active calls on the gateway.

Only thing to be aware of this is that this OID from memory only returns the TOTAL number of calls on the gateway, and doesn't break it down interface by interface.

It's a starting point anyway

I typically recommend loading the following MIBs:

• CISCO-VOICE-DIAL-CONTROL-MIB
• CISCO-VOICE-CONNECTIVITY-MIB
• CISCO-VOICE-IF-MIB
• CISCO-VOICE-DIAL-CONTROL
• CISCO-POP-MGMT-MIB

I also load the following if it applies:

CISCO-VOICE-ANALOG-IF-MIB

CISCO-SRST-MIB

CISCO-VOICE-APPS-MIB

You can find these MIBS on Cisco (

http://tools.cisco.com/ITDIT/MIBS/MainServlet?ReleaseSel=3835&PlatformSel=78&fsSel=1210)

Go with V2 MIBS. I believe the Cisco tool will also highlight dependencies. You'll need those referenced MIBS as well.

There is a lot of stuff in those MIBS. You will need to walk the MIBS and pick out the OIDs that address your needs.

Barry & William,

I will give that a try.  Thank you!
