Change the Web Components External URL in OCS

I was trying to change the external FQDN used by the Web Components server in OCS.  In the documentation it says that you need to run the following command:

Lcscmd /web /action:updateexternalpoolurls /externalwebfqdn:<ExternalFQDN> /poolname:<poolname>

This returns an error:

ERROR (0xC3EC7942): Invalid values specified for one or more
command line argument

The documentation is incorrect.  The correct command line is:

Lcscmd /web /action:updatepoolurls /externalwebfqdn:<ExternalFQDN> /poolname:<poolname>

How do you install it?  This from the MS Exchange Blog:

Let's assume I've downloaded the UK English (en-GB) language pack and stored it in the D:\UMLanguagePacks folder. On each server in the UM dial plan, run the following command:

exsetup /AddUmLanguagePack:en-GB /s:d:\UMLanguagePacks

...

Once this has been done, run the Exchange Management Console, go to the Organisation object and then the Unified Messaging object underneath it. On the UM Dial Plans tab, bring up the properties of your dial plan and on the Settings tab change the default language option to reflect your newly installed language pack. No service restart is required - at least, I never had to!
