TheTaker i did like you suggested...
If I dial the HuntGroup (502) it forwards OK to mobile
If I dial the Extension (509) it forwards OK to mobile
The automatic forwarding from external line doesn't work though still
I don't have a voicemail system - it is disabled in the "System" - but i still get a record about Voicemail..
I'm providing some information from the monitor if anyone can understand what is going on:
