> BTW: does it make sense that, regardless the DTLS roles, each endpoint uses usrsctp_connect() so both endpoints send a SCTP INIT and both reply SCTP INIT+ACK? or should just be a single SCTP INIT in a direction determined by DTLS roles? (sorry if this is off-topic, but I see that most implementations use usrsctp_connect() anyway so we get INIT and INIT+ACK in both directions and wonder if it's related to this issue).
This is fine and a not well-known feature of SCTP called *simultaneous open*. Definitely not related to this issue.

This is fine and a not well-known feature of SCTP called *simultaneous open*, making the code quite a lot simpler. Definitely not related to this issue.
