<p class="MsoNormal">Hi Ali,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Looking through the source code, its not that the port for I-CSCF is hard coded to 5060, its just that it defaults to 5060 if the following is set in the Kamailio.cfg file: dns_try_naptr=no which we had left it disabled.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Well I assumed I had all the DNS worked out, I had NAPTR records set for the P,I and S-CSCF.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Looking though the pcscf.cfg there is a setting for NETWORKNAME which is set to ims522.ims.org, and is a separate FQDN from the P,I,S-cscf FQDN’s. I always kept the NAPTR rec for ims522 as the same port of the P-CSCF (pcscf522) in DNS.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Two things I needed to fix:<o:p></o:p></p>
<p class="MsoNormal">1. Enable the DNS NAPTR lookups: dns_try_naptr=yes<o:p></o:p></p>
<p class="MsoNormal">2. Modify the NAPR for ims522 to be that of 4060<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks to you and Amar for the pointing to DNS.<o:p></o:p></p>
