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