<div>The sequence number is from the past. The first
SUBSCRIBE is sequence number 22 (check the CSeq header).
The second is 20. The third is 21. It appears as though
this is from the past, so it receives a 500.</div>

<p>Ok, I've had some back and forth with the linphone developers and
they contend that although the sequence number on the 2nd and 3rd
SUBSCRIBE messages start a new sequence this is legal as it is a
new conversation -- the "tag=" on the From has changed.</p>
<p>Are they right? (Notice that the tag= from asterisk also
changes).<br>
