Hi Ali,
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.
Well I assumed I had all the DNS worked out, I had NAPTR records set for the P,I and S-CSCF.
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.
Two things I needed to fix: 1. Enable the DNS NAPTR lookups: dns_try_naptr=yes 2. Modify the NAPR for ims522 to be that of 4060
Thanks to you and Amar for the pointing to DNS.

Hi Martin,
As Amar pointed out it may some DNS configuration.
You can check the DNS entry of I-CSCF with: $ dig -t srv <FQDN of I-CSCF>

I think you are missing the DNS part.

I can configure the P-CSCF to use 5060, and the I-CSCF to use 4060 and both come up listening to their respective ports when each module is started. But the P-CSCF is hardcoded to use 5060 for the I-CSCF.
Before I make code changes to the executable: Is there some additional configuration to allow for me to switch ports? Why is Kamailio IMS hardcoded and why not enforce it at the .cfg load time?
Thanks, Martin
