Monitor Active Calls over SIP Trunk

[hipgrpcisco1]

Hi Guys,

We are using CUCM 11 and we have a requirement to monitor the number of active calls over our SIP trunks. Currently, we have 4 SIP trunks that we wish to monitor. Ultimately what i want is to be able to see the total number of active calls for each of these 4 trunks. For example

Trunk 1: 6 calls

Trunk 2: 3 calls

etc...

I know i can see this information in RTMT, but i would like to be able to pull this data via another method so i can add this into our existing monitoring solution and also run some calculations on this data. Is this information logged in an SQL database we can query? Or maybe it can be exposed through SNMP?

Any insight anyone can provide would be greatly appreciated!

I use 'show call active voice compact'

Not sure if this is SIP only as we have no analog lines.

Hi,

You can use the trunk utilization feature of the CDR.

Also, it can be done using SNMP. Refer to the discussion below:

When we view the trunk utilization, it shows that it is always at 100% regardless of if there is one active call or 20. 

Not sure if it makes a difference but this is CUCM hosted on a UCS so a lot of the ios commands are not recognized. Also, the OID's listed in the article are not found.

I played with this a few months ago. I know when I set it up it defaults to having a single truck or on SIP a single channel. I had to specify how many I had. Then you wait 24 hrs and look the next day and it shows the correct percentage.

This can be done from RTMT. In the System pane to the left under "Performance" select this and a list of all CUCM nodes is listed. Expand this list and look for "Cisco SIP". This will list a number of actions that can be viewed. One of which is "CallsActive", which will show the active calls on the selected trunk. You will see all the trunks that are registered to that CUCM. If you do not see the SIP trunk you are looking to monitor then you will need to select another CUCM. If you have a bunch of nodes you can try this on each or go into CUCM Admin and see what the CM Group is for the trunk. This will be within the SIP trunk's Device Pool settings.
