Getting call set-up and call tear-down information 1

[Greenquest]

I'm trying to figure out how to get real-time information on when a call is being set-up and when a call ends. (for all calls on a Call Manager).

I'm trying to use this information for automated firewall control.

Anyone know how to get this information out of Call Manager?

Thanks

What version of CCM do you have? What type of gateways do you have (PRI on 6608, IOS gateways, etc.)?...

If you're just trying to find when a call started and ended, you can look up the CDR's via CAR (this must be installed on the publisher CCM) associated with that particular user or phone device - it will tell you when a call started and ended, both internal and external. CDR's are put in, I believe, at real time...it's the CAR reports, I think, that are a day behind. I stopped using CAR awhile back, because for call accounting it's not, shall we say, the most robust program out there.

Alternatively, if you're looking for something with more debug info, you can use the Q.931 translator in CCM Serviceability. But, I don't know much about your setup in order to actually recommend that...

Thanks TMH,

I'm trying to find a solution that will work for any customer that has version 4.0 and up.

Unfortunately the CDR records get produced at the end of a call, otherwise it would be perfect.

Can you tell me a bit more about Q.931 translator?

Hmmm I haven't used the Q.931 translator in awhile...it only tracks ISDN Layer 3 protocol messages, and it looks like it's only good for tracking outbound/inbound calls to and from ISDN-capable gateways connected to the PSTN, not IP phone to IP phones. So as far as real time start/stop of *any* phone call, you might be better off at looking at third-party call-accounting programs. I know some of them can do real-time info...

Anyone else with more experience with this want to chime in?

I guess you cannot get realtime from call manager cause the event is triggered on the CDR table after the phone call ends ...

Thanks for your help guys,

I'll do some research on the accounting vendors out there as you suggested.

I'll also see if I can get any of this information out of Call Managers JTAPI interface.
