From Your Free IP PBX 

Documentation: Extensions

The extensions refer to the internal phones attached to the IP PBX. Extensions have a double role:
a) The extension's number is the username used by your telephone(hardphone or soft client) to authenticate itself to FreeSentral.
b) The extensions number can be used to login in the interface to listen to voicemail messages and set forward options for each extension.

Call between extensions are made trough the FreeSentral server, free of charge.

After defining the extensions, one is able to create Groups and add extensions to each group, an extension being able to exist in more than one group. Each group will have it's own extension number of two digits. When a call will come for the group all the extensions in that group will be called. The first one that answers will take the call.
