You need to set From header when you are registering an account. As far as
I know there was no other methods to set From header (I tried it 2 years
ago).

I actually implemented setting a custom "From" user and display name for
pjsua_call_make_call();
however, I had to patch PJ for this.
Not sure right now if I've pushed this to my public repo, I'll check
tomorrow.
If not, I'll just post the changes here on the mailing list.

Best regards,

Andreas

You need to set it into header list before registration. And I made same
as @ Andreas Wehrmann , just patched it.

Okay, not in my repo.
I modified pjsua_call_make_call() and the pjsua_call_setting struct in
pjsua.h.
See the attachement for my versions.

All the best,
Andreas

OK, I will try that soonest and let you know the outcome.
Thanks a million for the support.

@Andeas, @Somedick

I managed to compile PJSIP with the changes Andreas sent
However, I must admit defeat in understanding how to set the new variables
set_from_display_name, from_display_name and from_user

I am using the demo program "simple_pjsua.c" as a base.

Could you enlighten me on how to set the outging from number.

Sure:
You need to look at how pjsua_call_make_call() works.
If you look  at the docs, you'll see that it takes a pointer to
pjsua_call_setting as third parameter,
so looking at the code at simple_pjsua.c, the code would need to look
something like this:

    /* If URL is specified, make call to the URL. */
    if (argc > 1) {
        pjsua_call_setting call_setting;
        pjsua_call_setting_default( &call_setting );

        /* set From userpart */
        pj_cstr( &call_setting.from_user, "12345custom" );

        /* if you'd want to set display name as well: /
        if( 1 ) / your condition goes here */
        {
            call_setting.set_from_display_name = PJ_TRUE;
            pj_cstr( &call_setting.from_display_name, "Doctor Who" );
        }

        pj_str_t uri = pj_str(argv[1]);
        status = pjsua_call_make_call(acc_id, &uri, &call_setting, NULL,
NULL, NULL);
        if (status != PJ_SUCCESS) error_exit("Error making call", status);
    }

@Andreas

Thank you for your help, again.

I have implemented your code, but whatever I do, the caller does not show up on my mobile with the spoofed number

I did monitor the sip exchange with the provider with wireshark, and could not see any mention of the spoofed number or name
The only thing I can think of is that I implemented your initial advice wrong. The simplepj zip file is my working code with the sip user/pass stripped.

To rebuild pjsua I did:
I changed pjproject/pjsip/include/pjsua-lib/pjsua.h line 855-913 to match your advice. I attach the file
I changed PJProject\pjsip\src\pjsua-lib/ pjsua_call.c replacing the pjsua_call_make_call with your code at lines 783-1052, file attached
Then did a make clean, make and sudo make install

I hope you can help.
Can you see where I failed?
