Hello,
I have setup an environment of OCS 2007 R2. I installed a Domain controller, OCS server and a mediation server. I have an PBX (Avaya IP Office 500). I installed the environment and used the following documentation to accomplish the connection to my Avaya:
https://devconnect.avaya.com/public/download/interop/OCSR2-IPO-PSTN.pdf
At the moment I can call from my Avaya phone to the OCS client. But when I try to call back I get the following error:
There was a problem with the calling service. Wait and then try again. If the problem continues, contact your system administrator with this information. (ID: 504)
When I look in the eventviewer of the I see the following error:
A SIP request made by Communicator failed in an unexpected manner (status code 80ef01f8). More information is contained in the following technical data:

Resolution:
If this error continues to occur, please contact your network administrator. The network administrator can use a tool like winerror.exe from the Windows Resource Kit or lcserror.exe from the Office Communications Server Resource Kit in order to interpret
any error codes listed above.
When I look at the mmc of OCS and I look at the events of the ocs server I see the following error:
An attempt to route to a gateway failed.
Could not route to Gateway OCS-MED01.*****.local:5061, the attempt failed with response code: Timeout.
Failure occurrences: 17, since 17-11-2010 10:23:21.
Cause: A gateway failed to respond to a request within allotted time or was unable to route the request due to some error.
Resolution:
Check whether the specified gateway is up and is properly configured.
I hope someone can help me with this problem.
