I;ve been messing with my asterisk to get a skinny phone working (still not there yet but thats another issue)

Anyway, I cant call *55 on my italk line at the moment. 2talk is fine. Before I go messing around since I havent changed dialplan so it should be no change - has anyone else had any issues with the italk voicemail - last would have used it about a week ago ok. So its either my changes or italk is broken.
