I just setup my freephoneline sip account on my asterisk server at home for learning. So far, everything seem to be ok. But, I thing I tried to change but does not work.
For outgoing call, can you change or hide the number. Instead of showing freephoneline, I would like to show another number/or block the caller id.
I did many tests but without succes.

Any idea or advice
Thank's a lot.
