3CX | Split DNS

Question

Hi Guys, 
 One of our customers uses a 3CX system and has a separate MPLS connection for it. They bypassed the link to 3cx and accessed their 3cx server through the internet. 
 Now they are requesting us to configure router traffic using the MPLS link, and if the MPLS link fails, we have to switch the request to the internet. 
 Anyone can help me with this?
