Hi Stefano,
maybe this helps you:
nua_invite(handle, NUTAG_MEDIA_ENABLE(0), TAG_END());
As far as i know this deactivates the SDP offer/answer engine for the call,
which would wait for user sdp and won't
send the invite if none is provided. You can activate the engine later in the
call with:
nua_set_hparams(handle, NUTAG_MEDIA_ENABLE(1), TAG_END());
By the way: if you destroy the handle directly after calling nua_invite(),
sofia will end the call. Maybe this causes some
trouble, two. Perhaps it would be better to destroy the handle in the event
callback.
