Hi Franz,

Thank you so much for the quick response.

I have looked into the kamailio-pcscf.cfg and found the line you have related to but I don’t yet know how to analyze this issue.

I have attached a capture file taken on the IMS server I be really glad if you can take a look and advise me how to continue.

Best Regards,

Rafael

Hi Rafael,

There should not be a problem with the VMware mage.

Regarding your question: you have to check kamailio-pcscf.cfg to recognize when and it how forward the SIP message towards the I-CSCF.

I guess it is the statement “t_relay();” in line 896.

You may provide a core tracefile (generated with tcpdump), then I may have aquick look ate your ise.

Betreff: Kamailio IMS virtual machine

Hello Mr. Franz

I’m trying to build a testbed using the VMware image you kindly have shared here: https://www.kamailio.org/w/2016/02/kamailio-ims-getting-started-box/

But when running the machine as-is I keep getting errors from the P-CSCF module and it doesn’t forward the SIP message towards the I-CSCF. Please see the following log:

root@server:~# kamailio -f /usr/local/etc/kamailio/kamailio-pcscf.cfg

Looking into the configuration files I couldn’t understand how does the P-CSCF  determine that it has to forward the SIP message towards the I-CSCF module.

Are you aware of any issue with the VMware machine you have shared.

Please advise.

Best Regards,

Rafael A.
