    Header?
    I ran a WireShark on an inbound call on a test PBX and test trunk with 3CXPhone set to Auto-Ans.. there appears nothing out of the ordinary.

    The capture shows 180 Ringing followed by a 200 OK a fraction after that, from my phone to the PBX, with SDP to set up the streams on the 200.

    Hi,

    Normally I am using this header "SIPAddHeader(Call-Info:\;Answer-After=0)" for grandstream. But I couldn't find for 3CX.
    Have you used like this header before?

    I am not aware of a Sip request/response for an auto-answer. the far end device is usually set for AA and does so when it sees a ringing request. If the far end device is not set to AA, i am not aware of a way of making it auto answer (unless it is set to allow page/intercom, which is a different setting altogether).
