Hi, solved: you have to fill out "Outbound Proxy" (same ip/domain as Registrar/Server/ Hostname). This forces 3CX to answer on Port 5060 to freeswitch and connection will be established. Else 3CX answers on the wrong (not opened) port. Best regard, Thorsten Am 12.12.2018 um 16:52 schrieb Thorsten Göllner:
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
