You need to deploy call-registrar on SailFin. When you run the install script for call-registrar, it generates the call-registrar.war file.
You need to register Web Space Server with call-registrar. After deploying call-registrar on SailFin, access the SailFin call-registrar at http://machine-name:8080/callregistrar/, where machine-name is the machine on which SailFin is installed. Here you need to specify the host name of the machine running Web Space Server.
As a first step in deploying call-registrar on SailFin, you need to install SailFin. Download SailFin compatible with your OS from https://sailfin.dev.java.net/. For the instructions to install SailFin, refer Sun GlassFish Communications Server documentation. Navigate to SailFin/bin folder and run asadmin start-domain command to start SailFin.
For installing SailFin, use a machine separate from the machine on which Web Space Server is installed. In the example discussed in this guide, the machine example132.com is used for this. Download a FCS bundle of Sun GlassFish Web Space Server 10.0 on the same machine, from https://webspace.dev.java.net/download.html. Use the Update Tool to upgrade the downloaded bundle from Web Space Server 10.0 to Web Space Server 10.0 Update 6, along with downloading call-registrar shipped with Update 6. After the download, call-registrar is placed inside the webspace-dir/webspace folder. You do not need to install Web Space Server here, but you need this for deploying call-registrar on SailFin.
