I have a special free voip did number that I use to trigger the callback.

I use a regular prepaid phone to make the call to that number. I receive a busytone and pbxes will call me back on my roaming free mobile. Than I get a dialtone.

In the beginning i was using caller id to trigger callback but depending on country different on no caller id were sent so sometimes I was unable to trigger a caller id.
For example using my dutch prepaid in holland it would sent caller id 06xxxx
when outside netherlands it could be 00316xxx or 316xxx
This meant settingup 3 caller id's to trigger a callback. pbxes only allows 3 so I could not use more. In case when outside nl the prepaid would not sent a caller id I could not trigger a callback.

So I endedup by getting a free voip did number. Anyone calling that number will trigger a callback to my roaming free cellphone. As I only know the number I never had a problem of someone else calling that number.
