Calls from Expressway-C to Expressway-E getting rejected after few seconds / MRA

Hello Gents,

I am running into an issue with a deployment involving Mobile Remote Access using Expressway C & E.

The components involved are as follows:
 
CUCM: 9.1.2.10000-28
CUC:  9.1.2.10000-10
IMP: 9.1.1.41900-1
Expressway: X8.5.1
 

In fact, Jabber clients on the outside network are registering correctly with the CUCM and can make calls to internal DNs with no problem. Here is the Expressway zone routing (Which is pretty standard for a MRA deployment):

EXP-E: CollaborationEdgeZone -> CollaborationEdgeZToTraversalSZ -> TraversalSubZone -> Zone003ToTraversalSZ -> Unified Communication Manager Zone
EXP-C: Unified Communication Manager Zone -> Zone004ToTraversalSZ -> TraversalSubZone -> Zone002ToTraversalSZ -> CEtcp-172.16.142.41

 

However, when calling from an internal DN (registered to CUCM) to a Jabber located on the outside network, I am getting a rejected call with response 487. It says it might be related to inter-working issues but I cannot see why.

The zone routing is as follows:

EXP-C: CEtcp-172.16.142.41 -> Zone002ToTraversalSZ -> TraversalSubZone -> Zone004ToTraversalSZ -> Unified Communication Manager Zone
EXP-E: Unified Communication Manager Zone -> Zone003ToTraversalSZ -> TraversalSubZone -> CollaborationEdgeZToTraversalSZ -> CollaborationEdgeZone
 
Only SIP is enabled in the deployment.
 
The call events related to this call are the following:

Could you post an Event log from Expressway-E? Did you check if a firewall is properly configured?

The Event Log output is present in the post. 

 

The firewall is properly configured as well.
