CNAM not showing on OUTBOUND CALLS

[akjon RooSho]

Hi,
I've bought SIP Trunk from SIPTRUNK.COM I've configured the CNAM there.
But when I make a call via SIP Trunk to any mobile number, It doesn't show the CNAM whereas I can see on Caller ID test that it has the CNAM perfect (like the image below)


I was wondering if I'm missing something in 3CX siptrunk configuration which is causing this.
If someone ever had this similar issue or if someone knows how to solve this. I'd be very grateful to know the solution to this.
Thanks in advance.
Regards

If you ask your provider about it they will inform you that it takes a while for CNAM to propagate.

It's like a database that other providers must also use (on the recipient side).

However, there is no guarantee that it will work on all occasions, it depends on the provider of the receiving party and whether the endpoint can display it
