DNS is fine. I flip the NAPTR records when I flip back and forth the 4060/5060 btwn the P and I.

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
