Call Server: H.323 Service Cannot Access Call Server
H.323 Service Cannot Access Call Server
|Problem Summary||Some HTTP requests from the Unified CVP Voice Browser to the Call Server are being blocked.|
|Error Message||Blocked by port blocking rule VoiceBrowser.exe Prevent IRC communication.
Blocked by port blocking rule tomcat5.exe Prevent IRC communication.
|Possible Cause||VirusScan is blocking ports in the range of 6666-6669, which are used in IRC communications. The application does not have to be listening on these ports for it to be blocked. If the application is assigned a client port in that range, the attempt to connect to a server using that port is blocked by VirusScan on the server machine. The connect attempt fails.|
|Recommended Action||Check the VirusScan logs for error messages. access the logs,VirusScan Console -> Task -> View Log You might find entries like these: 10/10/2006 3:15:01 AM Blocked by port blocking rule VoiceBrowser.exe Prevent IRC communication 10.86.129.138 10/10/2006 8:49:01 PM Blocked by port blocking rule tomcat5.exe Prevent IRC communication 10.86.129.211.
To view VirusScan logs
Exclude the Unified CVP processes from port blocking when using McAfee VirusScan on a system running Unified CVP Call Server. If a different anti-virus product is used, do the equivalent exclusions for the port blocking rules for that product.
