<br>
Would you mind getting a pcap of your DTLS traffic? I assume you are<br>
getting a Close because the clients are incompatible. These are the big<br>
ones I have seen with DTLS.<br>
<br>
* One side doesn't have use_srtp<br>
* DTLS v1.0 and v1.2 mismatch<br>
* One side requiring Extended Master Secret, other side not supporting<br>
* .... lots of other crazy stuff :)<br>
<br>
thanks<br>
