Hello Daniel,
sorry for the late reply (I was not aware of you response till some
days ago. I might have mistakenly deleted your message without reading
it).

The call is answered immediately upon reception of the INVITE and
immediately terminated with BYE.

This is not happening if you expect the profile to be cleared by
itself upon reception of BYE (it will only happen for calls longer
than 3 or 4 seconds from INVITE to BYE).

I tried that with the 1.4 branch and it works.
Thanks for your assistance.
