<div>Hello,</div>
<div>I have the following topology. </div>
<div>Kamailio as SIP Proxy and Asterisk as B2BUA. In Kamailio I
use rtpproxy for NAT users.</div>
<div>The problem that I have is the following:</div>
<div>-When the CSipSimple is registered the first call is always
unsuccesfull. The following calls are always successful. If
the application remains idle for a while the next call is
unsuccessful again. From traces I saw that <span
style="font-size: 12pt;">everything is OK </span><span
style="font-size: 12pt;">in signaling part.</span></div>
<div style="color: rgb(0, 0, 0); font-size: 12pt; font-family:
'times new roman', 'new york', times, serif; background-color:
transparent; font-style: normal;"><span style="font-size:
12pt;">-When I try with Zoiper and 3CX I have 1/20
successful calls.</span></div>
<div style="color: rgb(0, 0, 0); font-size: 12pt; font-family:
'times new roman', 'new york', times, serif; background-color:
transparent; font-style: normal;"><span style="font-size:
12pt;"><br>
</span></div>
<div style="color: rgb(0, 0, 0); font-size: 16px; font-family:
'times new roman', 'new york', times, serif; background-color:
transparent; font-style: normal;"><span style="font-size:
12pt;">In any case from Asterisk side these calls can be
seen as active but no media.</span></div>
</div>

maybe providing the sip trace will help us to see if something is
wrong there. Otherwise, it is hard to guess what is wrong, can be
the nat router in front of the phones, doing 'smart' sip alg.<br>
