Call Forward to Virtual Extention Fast Busy

Hi i am having a very frustrating Issue.
I have a FreePBX Appliance 60 Running PBX Firmware: 10.13.66-16 and Asterix 13
When i do a call froward to a Virtual Extension that we use for VM i get a fast Busy.
i can do a forward to an external 10 digit number and it works.
any ideas or suggestions would be great.

so i have solved the Issue i disabled Follow-Me and that fixed the issue. dont know if there is a better way but it worked.
