Jabber edge over expressway not working

We deployed an expressway-c and expressway-e construct (version 8.1.1) based on cucm 9.1.2 and cupx 9.1.1.




internally, jabber works fine while connecting directly onto the IM.




externally (over the expressway-e, placed into a DMZ) there is no connection establishment.




the only error i can see in the expressway-e event log is the following one:




traffic_server[3262]: Event="Sending HTTP error response" Status="403" Reason="Access Denied" Dst-ip="***ip***" Dst-port="60151" UTCTime="2014-05-15 05:43:09,846" 




...anyone out there with the same problem? ...any ideas how to solve this? ...would be very appreciated :-)

Hey Thomas,There are many

Hey Thomas,

There are many things that could cause Jabber to not be able to login successfully through MRA using Collab Edge. I would check out the following though:


Make sure that you have the traversal zone between the Expressway-E and Expressway-C setup for Force Encrypted so that is uses a TLS connection. Also make sure that both the Expressway-E and Expressway-C  have the 'Unified Communications Services' option under SIP for the Traversal Zone set to 'Yes'.


If this is already configured, then it could be a few other things causing this, but based on the 403 error, this is most likely the issue.

Hi ,I'm also not able to

Hi ,

I'm also not able to login to cisco Jabber MRA even from "ISO, Android ", my setup is CUCM 9.1.2 and IM version 9.1.1

but i already configure the Traversal Zone between the Expressway -E and Expressway -C to used TLS and is active between E and C it take littel time to make it TLS ON anyway, also i have Configure the "Unifed Cummincation manager " option to be "YES" under Traversal Zone.

the TLS verify mode On  for Cisco IM and presence but when i try to did it for unified communication not accepet and say "Cannot connect to "My publisher name". TLS certificate validation failed
