Cisco Jabber for Windows 9.6.1 - Installer switches


Hi All,

I am attempting to use the _cisco-uds SRV record to auto discover services in Jabber for Windows 9.6.1 using CUCM/IM&P 9.1.1

Our internal DNS servers are on a internal AD domain (example.local) which is different to our SIP ( or Email domain ( Based on the Cisco Jabber for Windows 9.6 installation and configuration documentation, I believe I should be using the SERVICES_DOMAIN installer switch

"Use the SERVICES_DOMAIN installer switch to specify the value of the domain where DNS records reside if you wish users to bypass the email screen during the first login of a fresh installation".

I uninstalled a previous Cisco Jabber for Windows 9.2.4 on the PC, therefore I used the "CLEAR" installer switch to remove any previous bootstrap information that might have been on the PC


Specifies if the client overrides any existing bootstrap file from previous installations. The client saves the arguments and values you set during installation to a bootstrapfile.The client then loads settings from the bootstrap file at startup"

"If you do not specify CLEAR, the client checks for existing bootstrap files during installation

  • If no bootstrap file exists, the client creates a bootstrap fileduring installation
  • If a bootstrap file exists,the client does not override that bootstrap file and preserves the existing settings".

Opened a command prompt

Changed the prompt to the location of the jabber msi file and performed the following command:

msiexec.exe /i CiscoJabberSetup.msi CLEAR=1 SERVICES_DOMAIN=example.local

After installation and launch of Jabber for Windows, I receive "Cannot communicate with the server" on the Jabber for Windows client

I ran wireshark during the launch of Jabber for Windows and I see ONLY the following DNS queries to the name server:


The SIP domain, which I suspect is cached from the previous install is being used instead of the SERVICES domain.

Am I doing something wrong?

Any assistance is appreciated.

NSlookup seems to show the SRV is setup correct.
