sip.automata and automata represents same thing i guess
Either its set as sip.automata=true/false OR automata(true by default)
Feature parameter(not feature tag) can be added to Contact header by
UA(mostly some answering machine/voicemail server/IVR/announcement server )
with value true or false
True : Call handled by answering machine/voicemail
server/IVR/announcement server
False : Call handled by human.
Mostly its seen when some server sends INVITE and add in Contact header .
Also this can be used in Register Contact header like sip.automata=false to
refuse to communicate with automation server .
Thanks & regards
