hello Daniel
thanks, finally i could do that, i was struggling with this because in
kamailio 5.4 there was not being created a socket on the bindaddr param
when starting kamailio. (that's why i even tried to start to listen on a
regular tcp socket to connect there an application)
But in 5.5 and 5.3 it does, so i could move forward and send the events to
an external application
best regards
david
