[App_rpt-users] Voicemail on allstar repeater??

Hi all, I have setup voicemail on our Allstar repeater e.g i can call the voicemail by doing a *69999 with 9999 being the voicemail. I can hear the voicemail menu but none of my dtmf commands are accepted.. I thought that if i used the dtmf transmit comand it may work but it still does not work... Any ideas on how to pass dtmf to the voicemail? Regards Anthony, VK2ACP ..
