however if I close the desktop application, then callers get a l-o-n-g silence followed by a busy signal, rather than my voicemail.
Although this doesn't seem to have anything to do with my setup, since the problem is when the Ap is not active... I was told to write in the forum for help... so please help

It was also having difficulty if set to 'follow me' to another number. It does forward alright, but if no answer, it doesn't revert back to it's own voicemail as it should (it goes to the forwarded to number's voicemail instead)
Looking forward to suggestions.
Thanks in advance.
