MRA - Remote endpoints



I have deployed Jabber through MRA which works fine for various clients, windows, ipad etc but am having an issue when trying to get endpoints to register to the CUCM through MRA. We have 3 MX300G2's which are all having the same problem.

When using the provisioning wizard for UCM via Expressway on the device it gives the error, incorrect username/password so it is finding the ExpresswayE and being passed through to the C and then trying to contact the CUCM. I have set up the MX300 as an end user and associated the device to that user and using the credentials of that user to try and log on.

I've switched off TLS between the CUCM and ExpresswayC to rule out certificate issues.

I see the following on the Expressway C,


2014-10-31T16:39:29+00:00 EUDC-Expressway-Core edgeconfigprovisioning: Level="INFO" Detail="Failed to find username or token in request."

followed by,

Any help would be appreciated.

I was looking for some help for this exact problem.

I was wondering were you ever able to find a solution to why you were getting these errors.

I have some TC Ex 60 that I am trying to register via the expressway and I am getting 401 unauthorized from CUCM. I know the username and password are correct. So I am at loss.


Thanks for any information you can provide.

Paul,First thanks for the


First thanks for the reply.

This was the document that I was following to verify my configuration but the confusion and the reason I believe I can not get it working is the CUCM Cluster I am working with is not in mixed mode security. This being a production system, I am unable to make modification to Cluster security, so I trying to figure out the optional settings  needed for TC endpoints proxying to CUCM using Cisco Expressway with CUCM configured with cluster security of "0"


Do you think this maybe the issue?

As side note: I am able to place the TC EX-60 on the inside of the network and it registers to CUCM with no problems.

Thanks for any HELP

I don't think that is the

I don't think that is the issue because secure registration is not mandatory. The logs will provide you some insight as to what the problem is. If you review the Tools section of the document you can review what logs are relevant to troubleshooting. Feel free to test the connection again and post the TC endpoint logs. I can try to look through them and see if I can determine what is going on.
