Hi, has anybody experience with 3CX-SIP-Trunks? I have installed Freeswitch and added an extension (trunk-1). On 3CX-Side I added a SIP-Trunk (generic sip provider) and I can see a succesfull registration. Now I make a call to Freeswitch and want to pass it to 3CX-Sip-Trunk. But when bridging to user/trunk-1 I get a "Originate Resulted in Error Cause: 41 [NORMAL_TEMPORARY_FAILURE]" error (with no delay). 3CX is installed as a VM in a Azure-Cloud behind NAT. I disabled local iptables and the Firewall-Test on 3CX is all fine. Freeswitch is on bare metal with a public ip. When making a call, wireshark on 3CX-machine shows the INVITE followed by "Destination unreachable (Port unreachable)". But I am not sure, if this is a firewall-issue or something else. Any idea? Thanks in advance, Thorsten
