3CX Cloud Setup not working with MyNetFone.

[jaime124]

Hi All,

My organisation is switching from a Kerio box PBX (on premesis) to 3CX hosted on Azure. I have created an instance of 3CX in Azure and this seems to be working fine. Inbound and internal calls are working fine but outbound calls to external numbers are failing. I have never set up a virtual PBX before so am unsure where I have gone wrong. I have added our SIP provider details in 3CX and followed the guide for setting up the SIP Trunk in 3CX. However I'm still unable to make outbound calls. I have created outbound rules that should enable outbound calls but I still seem to be missing something. Can you please point me in the right direction?

I have a pdf from our SIP provider (MyNetFone) showing what our packets should look like. An actual log from a call is attached. I believe there is something wrong with the IP our PBX is sending to the SIP provider. However I have already added our public IP into the contact field.

Has anyone else had this issue when configuring 3CX for MyNetFone and found a resolution?

Thank you.

Did you follow this document?

If so and it's not working, then you should be reaching out to MyNetFone. They can see the packets and tell you why it's not working.

I did. I have also reached out to them but haven't had a response as yet. I note that my logs look different to their document so I think maybe this setup document doesn't work for this provider?

Also inbound calls and calls between extensions work fine. It's just outbound that won't work.
