I know, the solution that the dispatcher brings is 1 long living tcp
connection from kamailio to asterisk, with kamailio keeping it alive.
Asterisk stores the ip/port to send the INVITEs to, as long as kamailio
or asterisk isn't restarted the ip/port combo (the same for all devices)
is still valid.
