<p class="MsoNormal"><span lang="EN-US">I’m trying to send a call to an AS via a kamailio S-CSCF (release 4.4.3). I’m addressing the AS by a distinct PSI:
<a href="sip:04325432101@domain.net;user=gsmr">sip:04325432101@domain.net;user=gsmr</a>.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">At the first try the S-CSCF sends a SAR to HSS and receives a successful SAA (tshark traces attached), but the S-CSCF rejects the call with 555 AS Contacting Failed - iFC terminated dialog.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">At the second try (a few seconds later), the S-CSCF doesn’t exchange SAR/SAA with the HSS, and now the call is successfully forwarded to the AS.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This problem is permanent, it is not the result of a temporary loss of connectivity between S-CSCF and AS.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">I checked the iFCs that I had configured at the HSS and I think, they are OK.<o:p></o:p></span></p>
