Solved Caller ID not displayed on called phone

[Harpau]

I installed a 3CX server to test the system extensively before deploying it in our company.
Everything works very well so far, but I haven't found a solution for one problem yet: When I make an external call from my system, my caller id is not displayed on the called phone.
I use an M-Net MGA as SIP trunk, which I have set up with the predefined M-Net profile.

Hi @Harpau

Are you sending out your main trunk number or have you defined a outbound caller ID in your extension settings?
Do you see anything on the called side?
You can check your activity log to see if the PBX is sending the caller ID to the provider. To do so navigate to Dashboard / Activity Log / Settings and set the logging level to verbose (to able to see the SIP messages).
Then make a test call and check the Activity log. Find the call and check the Invite from the PBX to the provider and see if the correct caller ID is sent. You can also use wireshark and make a capture if you are more comfortable with that.
If it does then your best option is to contact the provider and asking them why your caller ID is not passed along. Many times it is the upstream provider that does not show the caller ID but you need to ask your provider about that.
If the caller ID is not sent then check your trunk and extension settings and make sure you have the caller ID set up correctly.

Many thanks for your support. I have resolved this issue by using the Generic SIP-Trunk profile instead of the M-Net profile. Now it works perfect.
