> chan_sip does not process 400 response to an INVITE.
> This problem was observed during tests:
> - Diaplan runs Dial() to generate an outgoing call with chan_sip.
> - chan_sip generates an outgoing INVITE request,
> - UAS returns a 400 response (nothing wrong in request, this is a test)
> - chan_sip does not ACK first 400 response, it only ACKs second occurrence.
> - Dial() exists only after timeout.
