I am trying to setup OCS2007 with CUPS 7.0.2 and CUCM 6.1.2.

I followed the documentation that I found on the cisco web-site, but the integration is not working.

In attach you can find an overview of my configuration.

Does anyone have an idée of what I am doing wrong here?

Here are the links to the documentation I have used:

Thanks in advance.

From the log, CUPS sent successful response to OCS. But OCS didn't trust the message.

If you looked at OCS log, you should see something like this "Result-Code: 0xc3e93f1e SIPPROXY_E_INVALID_RECORD_ROUTE".

To fix this problem, go to OCS management control, right-click on "Front Ends" folder, go to "Properties > Host Authorization". Add the CUPS IP address to the list with the following options:

Outbound Only: No

Throttle as server: Yes

Treat as Authenticated: Yes

After applying the changes, restart Front End service.

I recommend you take a look at this book:

The book has in-depth explanation of CUPS and OCS. It also give you some real examples using OCS debug tools.

Also, take a look at my blog:

Thanks for your reply.

I have checked the OCS Configuration.

We already configured the hostname of the CUPS Server under the Host Authorization of the Front-End with the options Throttle as server and Treat as Authenticated.

So I assume that this is correct?

no, that is NOT correct. You have to following my suggestion to the letter. :)

ie. Use IP address instead of hostname.

On network layer, hostname and IP makes no difference as long as hostname can resolved to the correct IP.

On SIP, it makes BIG difference.

The integration is working now.

After modifying the OCS Host Authorization to the IP-Address of the Presence Server.

Many thanks for your help.
