Understanding MRG and MRGL

  Sorry for the basi question:

I am looking at our config in the Media Resource Group configuration, in that page there is a box that shows the "Devices for this Group" and it shows the "Available Media Resources".

It looks like the Available Media Resources are gathered from the menu items listed above Media Resource Group listed on the configuration page.

Is this correct?

When looking at some of those items, like "Annunciator" for example, there is no option to create a new one. Where do those items get created?

Also, how does a MOH server get created?

Understanding MRG and MRGL

What shows in the available resources are MTPs, MOHs, ANNs and XCODERs which haven't been assigned to any MRG.

The SW ANN, MTP and CFB are created via the IPVMS and thus only one instance can exist per service and per server.

You can only create any of those if your first delete them.

Understanding MRG and MRGL

If they are created by the IPVMS, does the name of the ANN or CFB get generated automatically?

Also, does the number of these get created automatically?

For example per my server, I will have a certain amount of ANNs, CFBs?

And, how do the MOH server get created?

Cisco Employee

Understanding MRG and MRGL

Yes, everything related to those media resources related to the IPVMS is created automatically once you start the service.

You get one MOH, one SW CFB, one MTP and one ANN per IPVMS running, you can only run one IPVMS per server.

Re: Understanding MRG and MRGL

Thanks for the answers Java.

Our current phone system has been upgraded a couple of times, and put on new hardware.

The current ANN, MOH and MTP resources have the IP Address of the original server in their name. These IP addresses were from the original config and are no longer accessabel via IP Address.

Would this be a result of the way the latest server was created, which it must have been backup restored to the new server causing all of the original names (with old IP Addresses) to carry over to the new config.

Does this make sense?

If the above is correct, we about to upgrade to UCS and the same company is going to do the implementation, which is going to be another build new hardware and restore config to new hardware.

Is there any way to control the name on the new builds to something more relevant to avoid confusion?

Re: Understanding MRG and MRGL

If they're working fine and registered you can just go ahead and change the device name of each media resource.

If the server on which they were, is no longer part of the cluster, you can try to delete them.

Re: Understanding MRG and MRGL

Thanks Java,

That is the thing, the server on which they were originally created no longer exists. The name reflects the old IP Address, but they are registed in the new cluster with the new IP Addressing scheme.

It seems the new server would have it's own IP Address in the name, but apparently when the server gets restored to the new server, there is no need to change the name of the existing resource.

Another question:

Do all physical devices have to have a MRGL assigned to them?

Is it isolated to physical devices only?

Re: Understanding MRG and MRGL

Once they are created they won't change, that info is retained and that is expected.

If you need media resources, then you need assign a MRGL to devices, and that applies to any kind of device.

I strongly recommend you to review the media resources chapter from the SRND.

EDIT: UNLESS you do not assign any media resource to a MRG and then they are in the default MRG which is like the partition, it's at the bottom of the list even if you don't see it. Then you don't necessarily need to assign a MRGL, but that's very poor design.
