[Freeswitch-users] is it possible to create a session between two extensions?

In FS, a session is connection between one extension and sip internal/external user. suppose I defined two extensions in diaplan/default.xml one is 2333, the other is 23334. (both are NOT locally registered endpoints) I am wondering whether it is possible to create a session with two extensions? like : original 2333-XML-default 2334-XML-default -jesse
