<p>Hello,</p>
<p>can you try with latest git branch 5.4? I just pushed a commit to
handle this case.</p>
<p>You have to compile from sources, like:</p>
<p> *
<a class="moz-txt-link-freetext" href="https://kamailio.org/docs/tutorials/5.4.x/kamailio-install-guide-git/">https://kamailio.org/docs/tutorials/5.4.x/kamailio-install-guide-git/</a></p>
<p>Debian packages from branch 5.4 are also built over night:</p>
<p> * <a class="moz-txt-link-freetext" href="http://deb.kamailio.org/#dev54">http://deb.kamailio.org/#dev54</a></p>
<p>Cheers,<br>

<div>Hi, I have updated Kamailio to 5.4 still there is an issue
with Cseq of cancel in case of cancel it is not increasing
cSeq</div>
<div>here are details</div>
<div>1. proxy a sends invite with CSeq: 102 INVITE and proxy b
route it to asterisk with CSeq: 102 INVITE</div>
<div>2. asterisk sends 401 Unauthorized with CSeq: 102 INVITE
and proxy b sends ACK with CSeq: 102 ACK</div>
<div>3. proxy b sends invite with CSeq: 103 INVITE and asterisk
sends 100 Trying and 180 Ringing with CSeq: 103 INVITE</div>
<div>4. proxy b relay to proxy a 180 Ringing with CSeq: 102
INVITE</div>
<div>5. proxy a send CANCEL with CSeq: 102 CANCEL and proxy b
sends CANCEL with CSeq: 102 CANCEL to asterisk</div>

not exist</div>

<div>Hi, Here is setup details</div>
<div>Kamailio Proxy a <-----> Kamailio Proxy b
<-----> Asterisk</div>
<div>Kamailio proxy b auth based on IP Kamailio Proxy a<br>
</div>
<div>1. Kamailio proxy sends an Invite request to
Kamailio proxy b with CSeq: 102 INVITE</div>
<div>2. Kamailio proxy b check again IP auth and sends
invite request to asterisk with CSeq: 102 INVITE</div>
<div>4 asterisk response with 401 Unauthorized with
CSeq: 102 <br>
</div>
<div>5. Kamailio proxy b sends ACK request with CSeq:
102 ACK</div>
<div>6. Kamailio proxy b sends INVITE request with CSeq:
103 INVITE</div>
<div>7. Asterisk sends 100 trying and 180 ringing with
CSeq: 103 INVITE</div>
<div>8. Kamailio proxy b relay 180 ringing with CSeq:
102 INVITE</div>
<div>9. Asterisk send 200 Ok with CSeq: 103 INVITE and
proxy b relay it to proxy a with CSeq: 102 INVITE</div>
<div>10. Now Proxy a send an ACK with CSeq: 102 ACK and
proxy b relay ACK to asterisk with CSeq: 102 ACK<br>
</div>
<div><br>
</div>
<div>Now asterisk is retransmitting 200 ok with CSeq:
103 INVITE and proxy a is sending ACK with Cseq: 102
ACK</div>
