[Freeswitch-users] CDR problem

Hi, I have a very initial FusionPBX/FreeSwitch 1.4.18 setup. I have added two extensions and multiple SIP trunks. Firewall config was a little bit tricky because FreeSwitch is NATed. But now everything works great. Now the problem: I got only CDRs for the first extension. Either for internal or external calls. Outgoing calls from the second extension are not logged. How can I find the cause? Greetings
