Help! Cant deacivate call fowarding

Any help would be greatly appreciated

I setup call fowarding from my hardware phone by dialling:

*720208838XXXX (This negates the voice prompts)

This works great… However

When I deactivate by dialing *73
External Calls no longer Divert BUT
Calls from Extensions still divert… I can’t switch it off… Help!!!

I have rebooted the snom 360, but asterisk is still fowarding extension calls… externals calls are not being diverted…

I have done an amportal restart, and the problem still exists… Help!!
