<div>ua1 (5978003 ) is register k1 </div>
<div>ua2 (5001005) is register k2 </div>
<div><br>

<div>When ua1 callout to ua2 sip process through k1 and k2</div>
<div><br>
</div>
<div>The problem is k2 server ACK not transfer to ua2 and k2
has received ack signals from u1 through k1</div>
<div><br>
</div>
<div>I ngrep sip process for k2 and k2 /var/log/debug </div>
<div><br>
</div>
<div>see the attached File ngrep_k2server.txt, debug_k2 </div>

<div>First ACK uri have ua2 number
<a>sip:5001005@xxx.xxx.xxx.xxx(k2):5003;ob</a> , is correct !!</div>
<div><br>
</div>
<div>2. Second ack not include 5001005 , again loop itself
; Route:
<a><sip:xxx.xxx.xxx.xxx(k2):5003;lr;did=763.941></a></div>
<div>loose_route Next hop:
'<a>sip:xxx.xxx.xxx.xxx(k2):5003;lr;did=763.941</a>' is loose
router.</div>
<div><br>
