Operation was unsuccessful

Hi,

 

I'm trying to set up Lync 2010 in a small lab.

I have a single server handling all the lync stuff, one domain controller, a SIP gateway and one client.

 

This far, I've been able to connect from the client to the Lync service.

When I setup a test call, through the SIP gateway - the client says

"Operation was unsuccessful".
The calling service did not respond. Waint and then try again. 
If the problem continues, contact your support team with this information. 

 

I have no idea where to start looking for the error.

Is this a typical Lync config error? Or could the problem be my SIP gateway not accepting the traffic from Lync?

 

Any pointers would be much appreciated!

Figured out that this was due to a misconfiguration in the SIP gateway.

 

Now I'm dealing with:

 

The Mediation Server service has received a call that does not support comfort noise from the Gateway peer, 1.1.1.1 (SIP gateway IP)
Cause: The Gateway peer does not support comfort noise.
Resolution:
Please ensure the comfort noise option on the Gateway has been enabled.

And this:

Unexpected exception occurred in the Inbound Routing Application.
Exception: System.DirectoryServices.ActiveDirectory.ActiveDirectoryServerDownException: The RPC server is unavailable.

Hi,

I have deployed Skype for business front end server 2019 and I'm able to receive calls from Cisco Meeting App Clients and Cisco jabber Clients but i'm not able to make outbound calls to the Cisco Meeting App clients and Cisco Jabber Clients. Can you Help me to sort out the issue.

Error log  : "Operation was unsuccessful".
The calling service did not respond. Wait and then try again.
