Expressway "C" UC & IM&P Status Inactive!


I am configuring Cisco Expressway "C" & "E" for MRA, but once I configure it the CUCM & IMP Status is showing inactive.

I have configured the following:

- All the required licenses are uploaded.

- Traversal Zones are Active between "C" & "E"

- I have even uploaded  the CUCM Tomcat and IM&P XMPP CA Signed Certificates on Expressway "C".

- DNS is configured

- MRA is enabled

Kindly tell me if I am missing some configuration or help troubleshoot any misconfigurations.

That used to be the case in x8.1, but now, when you create a traversal zone you have to specific if its a Unified Communication traversal zone or a normal traversal. Looks like you created a normal traversal zone. You will have to delete it and recreate it as UC traversal zone.

Is there any specific method

I can see another option Unified Communications Traversal so I'll try to configure through that.
