How to suppress SIP registration failures in the Sametime 8.5x client

I knew that this were somewhere, but I could not found it.... Next time, I'll know where to find it :-)

Problem

When the Sametime client fails to connect to the Media Server there is a pop-up such as the following: "Unable to initialize Computer, and it can't be used at this time.

com.ibm.collaboration.realtime.telephony.softphone.SIPPhoneException:
Processed unsuccessful response: SIP/2.0 401 Unauthorized"


Can this be suppressed?

Resolving the problem

You can add this line in the Sametime plugin_customization.ini file to suppress this pop-up.
