Based on your post it seems that you are in or near Kuman, Albania. Is that correct?
You say that you can’t forward to a cell phone number, but wouldn’t that number begin with 06? The 049681222 appears to be a Tirana landline? Is that number also listed in your follow-me?
In any case, if you dial the 04 or 06 number directly from your extension, does the call complete properly? If not, please post a log (including SIP trace) of an attempt to call that number from your FreePBX extension, while the system is otherwise idle.
If calling directly does work ok, the call is likely being rejected by your provider because of the caller ID. To confirm this, temporarily set Outbound CID for your extension to 038606806 and try calling the 04 or 06 number again. If it now fails, post a log.
If you can successfully call with the ‘spoofed’ number, we’ll suggest some other tests to isolate the trouble.
