VERTO

Verto is much simpler than SIP, it connects users directly registered to the same FreeSWITCH server. So, from FreeSWITCH dialplan point of view, is very similar to the "user" SIP shortcut, and you don't have to bother too much:

    <action
    application="bridge"
    data="${verto_contact ${user id}@${domain}}"/>
  

It actually uses the verto_contact API command to find the underlying RTC data needed to originate the call to the VERTO registered user.
