You just need to define an additional SIP domain in OCS and then you can assign that domain suffix to each of the new user accounts from the new company in your domain.

You'll also need to deploy additional SRV and Host records in DNS to support Automatic sign-in for users in that namespace, as well as update server certificates to include the proper FQDNs for the new domain as well.  You do not need to define additional FQDNs in the new domain for Web conferencing or AV services on an Edgserverv though, only the SIP FQDNs need to be added.

Take a look at this blog article for more details on external certificate guidance when adding SIP domains: http://blogs.pointbridge.com/Blogs/schertz_jeff/Lists/Posts/ViewPost.aspx?ID=79
