Incoming call on SIP trunk not going to voicemail

Hi all

I have a SIP trunk setup with my SIP provider (www.vox.co.za). Incoming calls work fine, except when the extention does not answer. Instead of going to voicemail it just hangs up. What I can not understand is, that when another internal extention dials and the extension does not answer, it goes to voicemail.
Below is my audit trail of when it happens:
