Question: Cisco CallManager

[richiev]

Hey all,

Just wondering if anyone here has used cacti with Cisco CallManager. Specifically has anyone managed to somehow graph CallManager telephony stats like Current Active Calls. There is a CallManager MIB on the Cisco website but it doesn't include active calls. I know active calls is available through windows perfmon data, but not specifically available via snmp without some kind of add-on to windows.
If no-one has done it I might look into seeing if it is possible and/or developing an add-on to do it.
Cheers.

What is running your CallManager box and what is terminating your voice line? Are they seperate?

If they are, you're going to want to get this information from the router that has the voice line, not CallManager.

If it's a PRI, there is an OID (can't remember off hand) for ISDN active calls that should work. Should give you the same info as a "sh isdn active" from the IOS CLI.

Yah, the voice lines are pulled down with snmp on the gateways as well as analog gateways such as vg224 & vg248s. no values unless the lines are in use - lots of blank space on graphs.

Heres' a weird issue. We have two gateways, both 3745 routers, same hw, sw & config (except ips & name of course) both with mgcp with the call manager. one of them has no config! I can telnet to it, but a sh run comes up empty. snmp does not work! The other gateway has a config and I can pull snmp values from it just fine. --wierd!

I graph the following on a Cisco router:
.1.3.6.1.2.1.10.20.1.3.3.1.1.1 for incoming calls
.1.3.6.1.2.1.10.20.1.3.3.1.3.1 for outgoing calls

It's all in the ISDN-MIB.

Sounds like a priv level problem with your username.

probably not, this is at the enable prompt. Anaywy, it is not a Cacti issue. Our voip guy is looking into it

Interesting.

Well, if you can't figure it out, let me know and I'll help you out, I'm a CCIE.

Also, there's some other stuff you may want to graph for CCM that could come in handy.

Registered phones: 1.3.6.1.4.1.9.9.156.1.5.5
UnRegistered Phones: 1.3.6.1.4.1.9.9.156.1.5.6
Rejected Phones: 1.3.6.1.4.1.9.9.156.1.5.7
Active Phones: 1.3.6.1.4.1.9.9.156.1.5.1
Inactive Phones: 1.3.6.1.4.1.9.9.156.1.5.2

yeah, these are available in the CCM-MIB but aren't of real interest to me.

I was hoping I could get active calls from CCM via snmp, as I know perfmon can access these kind of stats, but SNMP can't 'out of the box'.
Our current gateways are the 8 port E1 blades for 6500's (WS-X6608-E1), but we are soon replacing them with 3845 routers, so maybe I'll wait until we put the routers in before I start getting these stats.

I haven't been able to find a MIB for it (I was wanting the same thing). I guess I need to browse through the Cisco MIBs some more.
