Samsung PBX issues

Hi Guys

Well its a funny thing happening to certain clients that we have. Inbound calls fail intermittently.
All PBX's are connecting via LTE (MTN/Vodacom/CellC) so I dont think its a network issue.

On my side when I call the VoIP/PBX I just get a busy tone but if you look at a call trace it times out after multiple invites. This happens from all networks (Cell/Fixed/VoIP)

I am stumped.

I have tried changing keep alive times, enabling DMZ to the PBX

Anyone have any similar problems or any ideas as to what could be causing this
