-----------------------------------------------------------

We suspect that, when error 400 is received without INTEGRITY attributes, this response should be ignored.

It's unclear what the reaction of Astierks/pjsip should be in this case.
Retransmit, the same packet? Or re-transmit a packet with additional attributes ?

In any case, we believe the TURN procedure should not stop here.

> The configured TURN server is never added to the ICE candidate list offered via SIP/SDP
> The assumed reason is that, after receiving status 400 (Bad request) Asterisk stops sending request and shuts down the 
> According to the RFC, a status 400 does not necessary means the procedure has to stop.
> See: https://tools.ietf.org/id/draft-ietf-tram-stunbis-13.html#section.bid-down
> NOTE : The PCAP contains 4 requests,  these are for audio, video and their 2 RTCP counterparts.
> But each of those 4 are only tried once.
