Expressway AXL integration with CUCM

[dsalamanca]

Hello everybody,

I am installing an expressway pair, and one of the first steps is to create the integration with their CUCM cluster via an AXL user. When I do this part, I always get the following error:

Unable to communicate with 192.168.70.5. AXL query HTTP error "'HTTPError:500'".

If I write down a wrong password, then a credential error appears, but if I write it correctly, then I get this 500 error. Also, I only get this error if I use the IP address of the publisher server, if I use a subscriber, the cluster information is retrived perfectly, however, I don't know if I will have additional trouble later for using a subscriber instead.

I have seen some bugs related, but none with the expressway version 8.9.2 that I am using. Does anyone knows how to fix this?

By the way, CUCM cluster is 11.5.12900, I am not using TLS authentication with the CUCMs and I already have reset the AXL service on the Publisher.

Any help would be appreciated. Thanks in advance,

DS

Hi DS,

You'll probably need to contact TAC with the AXL and Tomcat logs for analysis if the service/server reset hasn't helped.

Hello,

What you told me made me remember that I reset the AXL service but not the Tomcat service, and that made the trick.

Thank you very much

Can you enable the logs on Expressway-C and then try to add the CUCM. And if you can provide that logs, i can help you to take a look at it. 

Or as mentioned open TAC with relevant logs and then they can help you.

Thank you Alok, the problem was on the CUCM side, however, thanks for your kind offer of help

That is not completely accurate. You can set the Expressway to use the RSA signed certificates. To do that see this video.  Configure Certificate Trust Between Expressway-C and CUCM | Secure Collaboration Integration
