when receiving refer
message avaya sip
trunk. not sure whether sofia-sip
allows users specify callback hook when refer
received. haven't found one.
i want add custom freeswitch
module handle refer
. how can force sofia-sip
cede control custom module while handling refer
?
having freeswitch, recommend using lua module provides event callback refer handling. can allow control want refer message.
mod_lua documented module in freeswitch. pain coding in lua easy or hard based on preferences.
