Inbound calls drop after 1 ring

[mobilesoundz]

Having issues with a new voip provider and the inbound number, it drops the call after one ring. I have sent this nuber to another 3cx install and it works as required so i know its not the provider, please see log below that might help someone to point me in the right direction. I have tried changing where the call goes from auto attendant to a voicemail but still drops after one ring
